channel_id is 8 bits on the client <-> server line, monitor_id is 32
bits though. What comment on limits? You need to use existing valid
IDs, otherwise it won't work. I don't see any other limitation.
I can change them (or just channel_id) to 8 bits if you want... I'd
just leave them like this myself though.

Not sure what you mean by this...
