Save yourself the trouble of implementing some sort of IPC mechanism over sockets, and give Pyro a swing: http://pyro.sourceforge.net In Pyro almost all of the nastyness that is usually associated with socket programming is shielded from you and you'll get much more as well (a complete pythonic IPC library). It may be a bit heavy for what you are trying to do but it may be the right choice to avoid troubles later when your requirements get more complex and/or you discover problems with your networking code.
