I would also be interested... however, at risk of threadjacking i'll leave the specifics to a different thread... but to OP, it would help if you could give a little more information as to what you're hoping to achieve.
for instance, is this for a game where the player launches their own instance of the server (like Team Fortress does it) or is this for a perpetually "on" server that's maintained by yourself (the IP owner) and accessed by other users whenever they're logging in (like an MMO?)
