there is a gateway between the media center canbus and the critical canbus.  the gateway buffers all the data from the critical canbus and rate limits any requests for data which isn&#x27;t broadcast regularly on the critical canbus.<p>You would have to get UID=0 on the canbus gateway to make requests &#x27;willy nilly&#x27; on the critical canbus.  Having UID=0  on the media centre would only help in making willy nilly requests to the gateway.<p>edit: clarity
