I can probably whip this together in a couple days, as I added 
the Bionic support before, but it's not something I need, so it'd 
just be a donation for you and others.  That's why I'm trying to 
figure out who exactly wants this and if others want to chip in.

Some of this stuff is on dub, but nothing that interests me or 
that I'd chip in with.  Good to see that RabbitMQ supports binary 
protocols like AMQP and MQTT though, would be nuts if it were all 
just text like STOMP or especially JSON/YAML.

I'm sure someone could put these together if the above stuff 
worked.  The question is who's interested in volunteering to help 
put this all together?
