My reply was not targeted at whether it is worth attempting to twist a CAN bus in to a star-topology.

I accept that the way CAN is designed is that it is a bus and that daisy chaining is the most reasonable physical implementation. I accept that this simplifies things and lowers costs in comparison to Ethernet. I agree that it makes little if any sense to try to wire it other than as a straight bus.

Instead, my reply was targeted at what I read (perhaps between the lines) in the replies prior to mine that seemed to express utter incredulity in why someone would want to do something so foreign.

I understand that there are plenty of other SPoF in the control systems. That doesn't mean that you like having any of them.

I also understand that CAN is in widespread use in automobiles, etc. But can we agree that automobiles aren't normally assembled by teenagers in training?

I especially want to thank crake for his amusing and informative reply.
