(I'm rather sure I replied to your first request, but I cannot find my own  
post anywhere, so I'll try again)

See the SocketServer module:  
http://docs.python.org/library/socketserver.html -- you may want to use  
ForkingUDPServer or ThreadingUDPServer. There is a client/server example  
at the end.
