Assuming your 40 clients represent real human users, and not automated
processes, I almost always approach this kind of problem with a web
application, usually a cgi script or simple mod_python handler. That way
I can spend more time solving the problem at hand, and less on
client/server design details or client installation/upgrade scheduling.
But then browsers and web servers are very common in our environment.

In that case, you might want to have a look at the SocketServer module
also. http://www.python.org/doc/lib/module-SocketServer.html
