Hey NZFF
The FSX multiplayer is far superior to FS2004, once you get it going. The only real way to do it is Gamespy though, my friend Ben and I tried Hamachi (it simulates LANs over the net) but we were unsuccessful. Anyway, someone set up a Wellington server and we flew on that. We got half way across cook strait and ben had to go to bed. Anyway, after that a random dude called aafif_41 joined the server INSIDE my Cessna, and we flew it together. We turned around and flew into Wellington intl. We didnt know how to talk to tower (there WAS one present), so I told him to squawk 7600 (because we had no comms with the tower), but from then on he couldnt control the aircraft properly. Seconds after that, the server went offline, so I never got to land.
What I'm trying to say (I'm very tired as I write this) is that FSX has the capability to be a REALLY good mulitplayer game, but it has flaws (connections etc). I'd really like to explore the shared cockpit more, so if anyones interested, get my msn address by PMing me and we'll find a time to play.
