I just dove into this several day ago for a small project.
On Linux it's easy -- it involves a couple of forks and other system
calls. Google for daemonize.py.
On Windows, a bit of searching seems to find a consensus that the way to
do something similar is as a Window's service. I'm just now looking
into how to register and start a service, and how to stop and remove it
later. Google finds lots of information on this -- perhaps I'll post my
result when I've pulled it all together.
