I'm not positive, but I think it is important. Only way to find out is to try (and measure signal integrity).
Since I changed jobs I don't have access to the RF / SI simulators. Perhaps one of our forum members could rig something up?

The advantage is then if a Jaguar fails, you just slap in a new one. I know that's just a fantasy, though.

Costs associated are:
microcontroller + FPGA per board
CAN transceiver+ Connector + terminators per leg
Not something I can justify for the KoP. Also, it takes a bit of work to make sure you don't get the bus latched into a dominant bit. Lastly, propagation delay is a concern.
