Ok, how about this.

Let's say I run 10 sessions on the same IP address and connect a client to one of those sessions. If I then do a 'LOAD_LEVEL' on the client will it then go out and connect to the appropriate session, looking for the same IP of course, or does it just think it is loading a local game level and not a multiplayer level?

If it will automatically load and connect to one of the other sessions then how do I get the engine to connect when I first start it without haveing to type in an IP address. I mean how can I pass the IP as a parameter to the engine on startup? I want the client to double click an icon and that's it. I don't want them to have to manually type in an IP address even if it is just the first time.

Anyways, is multisession on the same IP the way I can get multiple clients connected to various sessions and them switch them between them without the clients ever have to stop and start the engine?
