Oh my goodness! I forgot the fact that the cRIO has a serial port that can be used to do this stuff. If you use an absurdly high baud rate (with a heavy dose of custom code, of course) and hook up a crio to, say, an arduino over serial (hook up the tx and rx to digital ports 0 and 1), you could have a co-processor work. I'm going to experiment with this and i will keep you posted.
