A much simpler approach would be, in my eyes, to work on avoiding the use of PLIB scenegraph dependency in FlightGear wherever possible and to simply copy the remaining PLIB dependencies - mostly joystick, networking and GUI - into SimGear. The few patches that make their way into 'official' PLIB could easily be incorporated into our copy as well.
