Our code builds and runs not only on a Jetson but on x86 Linux, Windows and Cygwin and autodetects whether to use CPU or GPU based on the hardware it finds.
The bigger problem is going to be speed. Based on what we saw running on the Jetson CPUs I'm not sure RPi performance is going to be usable. But I don't have any specific tests to prove it, but I'd be surprised.

I went to the jetson release at makerfaire and talked to the lead designer. The architecture is quite different but speed increase is quite nominal compared to the pi. Thats coming from an intel designer.
