I had an idea about that.
Something similar to "ESR-Path"-Function for DVD-Videos and PS2-Disc.
If you insert a DVD-Video, or Fake-DVD-Video-Disc into your PS2, it could start an app instead of the DVD-Player.
Thus, people could map SMS as DVD-Player-Replacement (but lags IFO/BUP-Support for that case, in my opinion... :-/ ).
Same goes for PS2-Discs.
If one is inserted, it could instead also start e.g. cogswap.
Just a thought,...
But I don't expect it to happen, or not now.
