Certainly!
A few of us are compiling everything we can find on the current state of development of the various retargeting algorithms. I'm currently digesting the material related to the attack vector that BitcoinEXpress (a member over at bitcointalk) identified in KGW. It's purportedly been fixed, but it was a very serious vulnerability that would have caused a lot of damage to our blockchain and the SolarCoin project as a whole.
I know a lot of folks are anxious, the reason it's taking time is precisely because we all believe in this project and the amazing community that's evolved around it. We aren't going to copy-and-paste a solution without examining it first because the unintended consequences could be pretty ugly.
I appreciate everyone bearing with us, the most important thing to me (and the others involved in the project) is the trust of the community -- and we aim to earn that by doing everything we can to protect you and the integrity of SolarCoin.

I'm sorry if this has been brought up before, this topic has been in a lot of different forums.
Have you considered Digishield
http://www.digibyte.co/digishieldI know other many other coins I have implemented it, I have mined a few coins with it and I haven't seen anything wrong yet.
It sounds like you have been doing a lot of testing, have you found things wrong with digishield?
Also has there been any real talk about SolarCoin adding PoS (proof of stake) It could bring some big attention to SolarCoin.
With Proof of Stake (PoS) being an "energy efficient" method of securing a coin's block chain. Because PoS mining does not require the intense computing to secure the block chain, it instead requires a small amount of CPU power, and some coins in an open wallet, to create new blocks within the network.
Here is a clipped video from Nxt coin on PoS
http://youtu.be/jjGwnGEwZHwHere is Hobonickel (where the above quote came from) which is a Pow/Pos hybrid
http://wiki.hobonickels.info/index.php?title=Proof_of_StakeIf you add PoS to Solarcoin it would become one of the most dynamic Crypto's on the market in my humble opinion.
Solarcoin at that point would have 2 PoW and PoS,
PoW- Solar power generating panels
PoW- Mining network
PoS- Coin holders
One of the bigger drawbacks to PoS is hoarding because no one wants to give up their coins. So that drives up the price, but also makes it harder to get coins. The thing Solarcoin has that makes it a great PoS candidate is the premined Gen pool. With the large chunk of coins premined and given out for solar power generation, That solves the hoarding problems of other PoS coins as well as drives more people to redeem coins for solar power. Its also good to mention it would be important to keep the premined out of receiving PoS rewards, simple keeping them in cold wallets.
Im not a promoter of any of the other coins... I could care less how the coins used for example proform... They are only used as a reference... Im all about making Solarcoin the best it can be!!!!
