It is possible to do this with Pyro.
I think Pyro can "auto-background" (my terminology not theirs) if you
allow it to do threading. Otherwise, you could handle requests by 1)
putting Pyro in a thread you manage or 2) a GUI timer calling Pyro's
daemon.handleRequests(...) fairly often.
But I hear nothing but good things about Twisted, and your code works,
so I say find some bigger fish to fry (especially since I can see
potential issues with each of the above options...).
