The can protocol spec is included with TI's software development kit. Not sure if its still available. I couldn't find it from IFI.

They would configure themselves when they booted up within 200ms for the 5hz stuff and 50ms for the 20hz stuff, with no additional code to detect and reconfigure a reset Jaguar.

I think you'd run into bandwidth issues with the serial bridge with that scheme.
