Yeah this is a good point, if you are tightly integrating the linux bit to the flight controller bit you will get some benefits here, I was focusing primarily on the topics other people keep mentioning like compressed video feeds which don't require that sort of integration.

It is certainly an interesting project, though personally I'd be more apt to buy/build a BeagleBone Black cape to achieve this sort of thing over a Raspberry Pi board.
