I don't see what the problem is?
In the original context of this thread, which was to do with computer to machine controller interfaces, magicniner's claim is correct.
In the case of CS-Labs they use it for inter-module communication, which is where it excels.

CANbus is a very resilient system, and can be very fast, however nobody uses it as a communication method between a computer and CNC machine. You could use it for realtime operation if you designed a suitable internal slot card that the computer could access directly and control in realtime, but you're then into a very glorified parallel port like system.
