Hi,

Before choosing a framework (pyro, socket or other) you should know
how you want to communicate. 

The easiest is "client-server". There is one server and several
clients connect to it. 

Peer to peer: There is no central server. All can talk to each other.
The problem is: How to find the other? If there are on one computer
this is easy: Just write files to a directory all processes know.
But if you want to talk to other computers, you need to know their
IP addresses.

For the communication UDP, TCP or HTTP can be used. I would not
use HTTP (XMLRPC or SOAP) if you don't need to. UDP is stateless,
and can be used for broadcasts.

I would use pyro or the socket module.

HTH,
 Thomas
