Hey PilotTJ,
Sounds like both people simply need the same plane, and I believe you need a co-pilot seat. Then when you link to the other flyer, you select either the pilot or passenger mode. If passenger, then when you are flying, you watch the controls move on their own and you simply take in the flight.
Its pretty cool. I havent heard about it in ages, since FSX came out. I'll see if there are any other things to learn about this that will be required.
