Would be nice to have the option within piplay to select a tracker source.
Take TrackIR for example.. Currently to use trackIR you must disable the HMD tracking, then use another program such as Freepie to make TrackIR show up as a mouse view or something, then you have to make the game use that instead of looking for tracking data from the headset which depending on the game can be a real PITA.
Instead just make Piplay compatible with TrackIR just like it were itself a game, and piplay just uses its data for tracking instead of the HMD gyros.
Seems like it would really simplify things and open up more options.
