Now raised the bounty to 1.5 BTC (+0.25 BTC bonus)!  That's pretty reasonable I think.  $660-$770 at current price of $440/BTC.  And it's a pretty fun project that will be widely used after you make it!

Any takers?  All the info you should need is in the OP.  Just get started, maybe put it up on Github during development and take my money!

Anyone else want to contribute to the bounty?  If so state the amount in the thread.
