the second one, I was using the strategy in the thread about 'how to last longer' and it works really well, until your luck runs out
but that was without the script and I noticed every once in awhile the transaction fee would go up if I didn't have enough confirmed coins obviously, so I would go do something else for awhile and come back, does this script check for that?
EDIT: i went back and re-read the code samples here and it looks like they take into consideration unconfirmed coins which would make the fee go up I think (?)
I was also wondering about the blockchain idea so I can screw around with it from work, I may do that in my spare time. It seems like they have an api that works with bitcoind so you would just point your script to blockchain.info with your identifier (not the shortlink) and the password along with port 443 instead of localhost and it might work the same.
I have yet to actually try it because all my wallet stuff is at home and I don't have any coins in my blockchain account so don't quote me
