You might take a look at my asyncproc module, available at
http://www.lysator.liu.se/~bellman/download/asyncproc.py
Specifically the Process class. It doesn't do exactly what you
want, but maybe you can use it as inspiration for doing it yourself.
It requires the subprocess module, but I have successfully used
it under Python 2.3.2 with subprocess installed locally.
