I spent hours last night looking for flight sim multiplayer servers and didnt find any permanent servers, instead I found this which is quite a good idea...

What these guys have done is make a flight sim server and given it away, but when you start your server it advertises itself in a client called FSHostSpy... and others see it and join you, or start their own server.
So FSHostSpy lets you find a game... but there is a free server that goes with that somewhere if you want it.

Naturally the latency is low and servers come an go but I managed to group fly for 4 hours last night...
Perhaps there are better alternative?
