Freeverse succeeded in very little time to make use of this feature in a special version of its software Moto Chaser and all functions perfectly. The display is done on the screen while the iDevice (that no longer displays anything) is used as remote control.
Of course, since Apple have not made this thing official, no software using this library can be made available on the AppStore, but this is clearly foreseen and they will prepare it in the next few months.
A note to finish: it is much more pleasant to play Moto Chaser on an iPod Touch V2, Apple having pushed the frequency of the processor well beyond the other iPod touch and iPhone. One speaks about 532 MHz compared to 412 MHz.
