I've had a lot of problems with multiprocessing, too, especially if combined with subprocess. If you're interested, you could have a look the cross-process communication in veusz's embedding interface which uses sockets (sending pickled python objects). Pipes don't work very well with Windows as they're not proper file objects (you can't use QSocketNotifier on them). Server end: https://github.com/jeremysanders/veusz/blob/master/embed_remote.py Client end: https://github.com/jeremysanders/veusz/blob/master/embed.py It's a bit tied in with the main program, but should be fairly clear.
