Here is my opinion (Crowd runs away).
I play a game called BattleZone2. It is quite popular on-line which is why I think this would work. First off there is only one server. Then there are rooms. You can either create or join a room. If you create a room you can set the ping limit (How high one person's ping can go.), password protect, kick or allow people to enter. I think that is pretty simple and should be able to work, because there is only one server and you just have to worry about rooms.
