For some reason I was thinking that my joining messages together there could be less data sent over RS232. However, the whole arbitration ID is necessary for every Jaguar, so I guess it wouldn't actually reduce required throughput.
Now I'm just fantasizing here, but scheduling status messages to be periodically sent and stored until retrieval could be a way to get around it. I have the feeling, however, that one could not use a motor controller for this.
