One would assume that the CAN pass through circuitry is sufficiently removed from the motor driver so that even a "blown" Jag wouldn't bring down the entire network. Even if that is the case it seems like this configuration could lead to a really tough time debugging your electrical system.

Eh, not really. CAN is reasonably fault tolerant. I'd be more afraid of a cable coming out or a device on the bus going "babbling idiot mode" than one Jaguar electrically disabling others.

Quoted for Truth. Standard CAN usually has 120 Ohm termination resistors on either end of the bus.
