I am also very interrested in a GPS-interface. I guess one would have to change /dev/ttySwhatever to a named pipe
(or even to /dev/null) to avoid having the player tie it up?

My wishes for GPS-interface:
1) I can enter a list of "waypoints" to the application, and it
will "beep" when approaching one of the waypoints
2) An on-screen display of speed/direction/position/time
