Great! It'll be a big help to offline use if I can restart my computer and load up Armory quickly.
Fantastic! Very happy to see results like that - especially measured in msecs 
For anyone waiting patiently (or impatiently) for the updates, here's some good news for you:

That's a major milestone for the new "persistent blockchain" stuff. It means that the DB successfully tracks all balances, even across reorgs. Given how little the blockchain utilities interface has changed, integrating this into the GUI may not be ridiculously difficult. Though, I won't put a timeline on it because I've been wrong so many times before...

awesome, I thought that serializeAscii() function looked promising
I'm working on it currently, and I also started browsing through qtdialogs.py to see what the GUI is actually doing on the backend to save the transaction files.
So the key once I get the actual transaction data is to dump it into a file called *.unsigned.tx so the offline wallet will recognize it. I was wondering about that as well, thanks! And here I thought the hardest part would be pulling the data in from my DB.. then I remembered about python-mysqldb wrappers
Edit:
Thanks a ton for the input, I have almost everything done now, just doing cleanup of my code and adding DB update stuff but I have all the tx file I/O setup. It was really simple once you told me about the serializeAscii() function.

I was working on my script and everything is going well
following the samples as you suggested was helpful. What I'm stuck on now is converting the createTxFromAddrList.py to make it so at the end instead of signing and checking etc, it would export the unsigned tx file that I can copy to my offline wallet. Basically everything works perfectly how I want it to build the transaction, but I am having a hell of a time finding how to export the details to a tx file.
So up to and including:
works well. and it prints out a lot of details showing where the unspent outputs are coming from and where they are going etc. I am trying to do this while having a hell of a time with the documentation so finding the right functions becomes a bit more challenging.
I also have the other side setup (using cli_sign_txdp.py as an example) to fit exactly how I need it to, just having trouble with the saving of the unsigned tx file.
Anyone have any suggestions?

Open a *.unsigned.tx file for writing and use the txdp.serializeAscii() method to dump it in the BIP 10 format which will be recognized by Armory GUI or cli_sign_txdp.py script.
Also note that since the Armory GUI does most of these things, you can probably find examples of what you're looking for, by simply searching the Armory codebase. I haven't done it, but I'm sure if you search for "txdp" in the ArmoryQt.py and qtdialogs.py, there will only be a few hits, and one of them will be serializeAscii() and another one unserializeAscii(). I use ASCII/text for the encoding so that the data could theoretically be copied into emails, like ASCII-armored PGP data.

That's an amateurish problem that only happens with custom implementations of ECDSA. You have to use a random number when calculating the signature, and every basic implementation of ECDSA guarantees this (at least to the extent of the randomness it can pull from your system). The problem there was people hand-rolling their own and not realizing that reusing "random" numbers when signing different messages with the same key reveals the private key.
What do you think of this? Is it safe? (Or is it too new to say?)

this is helpful for sure!
etotheipi - I spent the last hour or two going through the example scripts, I am sure I will be able to get it going how I want, if I need to discuss this more, I may split it out as you suggest.
etotheipi, are you watching the development in bitcoind regarding the importaddress RPC method?
Commenting on that issue, it got me thinking that this is perfect for Armory (and all other wallets that interface with bitcoind/qt).
Just let Armory handle the wallet/private keys, and then add the addresses to bitcoind using this RPC method, and you can query it for transactions involving the addresses in question using listtransactions. This saves the double work of first letting Bitcoin sort everything out while it's downloading the block chain, and then having Armory scan the blockchain for transactions again.
Armory would be able to start instantly, and update the balances as bitcoind updates the blockchain and the list of transactions referencing the addresses added via importaddress.
Would this work do you think?

When exactly does it crash? Does it not open at all? Or does it start to open then crash immediately? Do you use a native language other than English? The most recent version had an issue with non-ASCII/non-English characters. If so, you can go to the downloads page and try 0.87.2. Many users have reported that working even when 0.88.1 doesn't.

As soon as I finish this RAM upgrade, I will have time to address these things. Getting closer!

Sorry for the lack of info from my side!
i'm using a German W7 Ultimate so i could switch to english (will try later)
i can start it and it loads the blockchain (armory-bitcoind / manual-bitcoind makes no difference at all crash wise) up to a point where it need ~2.5G of real working set RAM. Then it just crash.

Please note i closed EVERYTHING i could to bring down real RAM usage of my system to around 1.4G of 8.
This laptop is rock solid for everything else. It's running hours every day, with RAM hungry VM's, games and what not.
Will try older versions again but like i said... it's crashing for months.

well... for me it still crash on every try.

- i have 64 Bit win7
it worked fine up untill 0.85something (i think).
This is the case on my Laptop AND on my PC (both 64 + 8GB) and i pretty much gave up for now...

Have you completely uninstalled and reinstalled? Sometimes the installer doesn't replace the old files properly when you are upgrading. I've tried multiple things to fix that, but it doesn't work.
as far as i know - yes.
so could I actually load the chain and scan for up to date transaction using this script without actually loading the GUI to scan the chain?
basically add a step to the beginning process of script to load/scan the chain (assuming that bitcoin-qt is currently loaded and up to date), then continue on with my previous logic?
Also, were you meaning that:
is replaced with:
to put armory into online mode and scan the chain?

That's correct. Everything the GUI does could be done from python scripts. In fact, you could think of the GUI as one big python script that simply uses the utilities provided by armoryengine.py (and the massive set of underlying C++ utilities). I've tried to keep the bulk of the functionality in armoryengine.py so that you don't have to import any Qt libraries in order to script it headlessly like this. There's still lots of example code in ArmoryQt.py and qtdialogs.py that could be useful, but everything that Armory GUI can do, can be done through scripts without any GUI interaction. If you run the cli_sign_txdp.py script, you'll see that it does the same thing as GUI, but through a text/terminal interface.
To continue discussion on this, it might be worth starting a new thread, to help aggregate this kind of information into a single place for others wishing to do scripting.

Check BitcoinArmory/extras/createTxFromAddrList.py. Also sample_armory_code.py in that same directory has a lot of useful stuff. Admittedly, some of the examples, including createTxFromAddrList.py, uses an old version of the blockchain utiltiies -- for instance, BDM_LoadBlockchainFile() no longer works/exists. If you see this:
Other than that, I think everything is the same, so you have an almost-full solution there! Also check extras/cli_sign_txdp.py which can be used on the offline computer to load your wallet, load an unsigned transaction, unlock your wallet, get your confirmation, and then sign it for you. Try it out! I made both of these to help scripters like you

Have you completely uninstalled and reinstalled? Sometimes the installer doesn't replace the old files properly when you are upgrading. I've tried multiple things to fix that, but it doesn't work.
well... for me it still crash on every try.

Check BitcoinArmory/extras/createTxFromAddrList.py. Also sample_armory_code.py in that same directory has a lot of useful stuff. Admittedly, some of the examples, including createTxFromAddrList.py, uses an old version of the blockchain utiltiies -- for instance, BDM_LoadBlockchainFile() no longer works/exists. If you see this:
Replace it with this:
Other than that, I think everything is the same, so you have an almost-full solution there! Also check extras/cli_sign_txdp.py which can be used on the offline computer to load your wallet, load an unsigned transaction, unlock your wallet, get your confirmation, and then sign it for you. Try it out! I made both of these to help scripters like you
Code:
BDM_LoadBlockchainFile()
walletObj.setBlockchainSyncFlag(BLOCKCHAIN_READONLY)
walletObj.syncWithBlockchain()
walletObj.setBlockchainSyncFlag(BLOCKCHAIN_READONLY)
walletObj.syncWithBlockchain()
Replace it with this:
Code:
TheBDM.setBlocking(True)
TheBDM.setOnlineMode(True)
TheBDM.scanBlockchainForTx(wlt.cppWallet)
TheBDM.setOnlineMode(True)
TheBDM.scanBlockchainForTx(wlt.cppWallet)
