Pretty much. There was talk earlier of faking out the player to make it think it was connected to the physical serial port, and instead connecting it to a virtual serial port, allowing us to write serial commands to the player and also being able to open the serial port device from apps (gpsapp). I'm not sure what the conclusion was on that idea, but that would enable both Palantir (and Emphatic, I believe uses serial commands) to coexist with gpsapp.
