ATC traffic and nosecam for IFE
The nice aspect of having ATC traffic or nosecam feed streamed through IFE is that it builds on the romance of flying. Satellite TV could been seen as simply placating you while you are "suffering" through the flying experience whereas ATC and nosecam add to the fun of flying and are specific to flying (you can't get them at home). I hope B6 picks up this idea from others that have tried it or use it now.
