After this (mostly fruitless) discussion, I decided to just use serial with a max232 to reduce voltage. The motherboard most likely won't need to receive input, and will send maybe 120 bytes a second back - note this is the current plan and as soon as we have a max232 we can check what kind of baud rate the cRIO can actually handle. I see no reason it can't handle a bit a millisecond.

if you have any better ideas I'd be happy to hear them
