I'm doing a little bit of work on the client/server branch. I'm sure that a select() server (also in Python) should be more than fast enough for this. More importantly, I feel it's the most friendly networking method to beginners (which is a good part in my decision to do this).
If I decide to get really motivated I'll merge the branches tonight, as I don't see myself working on this much in the next few days.
If at any point, anyone wants source for whatever reason, let me know. If it gets moving I'll probably set up a page for it (maybe sourceforge?).
