Whether or not you run multiple rabbits (or couches, or ejabberds, or
riaks), the Erlang VM itself has a singleton in the portmapper daemon
(epmd) which is started by the first erlang application that runs on
the system. I don't think there is any problem running multiple
instances of an Erlang application such as RabbitMQ on the same box,
but using branch nick as a queue prefix seemed to provide a sufficient
level of isolation when I was working on U1.
