When you say 'peer to peer', is this still with Python sockets? It
sounds like what I am looking for! Or, creating a server and both of
us being clients: I have a server (not my own machine, but I rent
space on an iPowerWeb.com server) so I could do this, but I would have
no idea where to start. Sounds like the p2p connection is the best
one.

I need a lot of keyboard interaction and popup dialogs with lists and
input controls, and my server does not have Python on it. Good
thought, though; maybe I could strip this one down and port to js...
