Cool stuff! I have done some python network stuff for a small robot. I wrote a client in python that used TKInter for a gui. The client talked to a python socket server running on another machine that in turn connected to the robot via a blueSMiRF. It allows real time control over the web. It was a really fun project.
edit: I forgot that I didn't use TKinter for the client GUI. It was PYGame.
