I2C advice

I am on a Formula SAE team and we are doing something similar to this and it works really well.

Also, Teensy 3.1 has CAN built in (minus a microchip for the i/o for CAN) and that has something like 22 analog ins, so if you are reading lots of sensors (like the Formula team I am on) you could use that to read sensors too.

Have you tried writing to non-Jaguar CAN devices on the cRIO? Or to arbitrary CAN devices on the roboRIO? WPILib does not currently have any user APIs for arbitrary CAN devices/traffic. This seems substantially harder than just getting I2C to work on the roboRIO itself.
