I was thinking of a similar project a while back using the game engine in  blender(although I'm sure there's other software, this was something that uses python, and is fun to play/work with), but since there are so many ide's it went to the back burner.

I posted a basic outline of my idea to list a while back, I think I still have a copy of it, but the pseudo code is lost in the digital ether after an os problem.

I'd be interested in working on a project like this with you if you're interested.
