So what would be great for us, and probably in general as well is if we could "share a ride".
One would need two rigs and two VR sets, but since FS2 can export its position through a port (at least so I understand from the menu), then all it would take is the possibility to receive such data.
Then one could put two rigs on the same local network, one is the one with the pilot, a "master" and broadcasts the position, the other is "slave" and is used only for viewing as a ride.
Then it becomes easy to be the WSO in the F15 (for example) and enjoy the ride. Of course the terrain in the second rig would condition what is viewed, but that's easy to fix.
Next could be collaborative or adversarial gameplay, but that's another challenge altogether.
So I put it out there, if it happens, great, if not great anyway.
