Multiplayer Information relay

Apparently, there used to be a mode in FS98 whereby an observer could join a pilot during a flight in the cockpit of the aircraft.I have never seen this option, but it brings up a question.For instructional purposes, teaching pilots to fly, is there a way to allow the instructor pilot into the cockpit of the aircraft the student is using? I have read the Multiplayer SDK, but C++ is greek to me.If not the ability to actually join the pilot in the cockpit, are there any A variables that could be passed to the instructor via multiplayer in respect to student control inputs, and vice versa to show the student control inputs for a specific manouver?Steve
