Please do yourself a favour and have a look at pyro. pyro makes
InterComputer and InterProcess Communication a snap. And it allows you
to push around Python Objects not only between processes, but
computers.

Maybe it solves your problem much easier and even more than you want to
solve it now by being able to use more then one computer.
