I know I'm not actually involved in FlightGear development, but please bear with me anyway :) When it comes to multi-player flight sim, one should keep in mind the virtual air traffic control networks out there, like VATSIM <http://www.vatsim.net/>, IVAO <http://www.ivao.org/>, and so on. These all have an existing server infrastructure with existing protocols. Now, this doesn't in any way invalidate other multiplayer approaches. But if interoperability with the above-mentioned systems were available, that would make Flightgear an option for those who want to fly in such a simulated controlled environment; and also open the door for flying together with users of other sims. > Regards, > Duncan.
