Simple Demo

Since it popped into my head, might as well note it.
A very quick and simple demo could be done by having 2 or more chips linked with the CAN network along with using the onboard LEDs and buttons. A simple master node could be created that counts the number of times a button is pressed on ANY of the chips (i.e. the number of times messages are passed to it) that are connected to the CAN bus. Could be further expanded by telling the other chips that the master node had recieved the message, or could broadcast the new total count on the master node etc...
