"CAN network support - god no. This jumps into the realm of medical systems, elevator controls, and passenger vehicles."
When I see "CAN network support" I am not thinking of controlling those systems, but rather, having the ability to read those systems ... or in the case of a device like a VAG-COM, being able to set new values, etc.
I agree that I would not want amateur tie-ins to critical safety systems like elevators and bridges.
