Windows doesn't really have daemons the same way POSIX does.  It has, 
instead, "NT services".  It would be super excellent for twistd to 
support these somehow.  Cory Dodt did some work on this years back, I 
think, but it never reached a point where it was suitable for inclusion. 
It might be interesting to review that work and see if someone can pick 
up where he left off.  You can find his code in svn in 
/sandbox/moonfallen/ntsvc.
