That makes far more sense using the Pi is a coprocessor and sending small amounts of data back to the RIO. CAN bus will handle that no problem, though unfortunately the implementation of such a setup is where we leave my realm of expertise.

From what I've researched, the Pi will need a separate CAN module, as it does not natively support CAN. However, it has hardware support for SPI and I2C built in, as does the RIO. Those seem like a more accessible method of communicating than CAN.
