Ok, so it's a bit more complex: each queue resides on a single node. As
a result, if that node fails, then the queue and its contents are lost.
There are a number of ways of working around this, ranging from
publishing to multiple redundant queues, to the pacemaker work
(http://www.rabbitmq.com/pacemaker.html), to experimental work in
development on mirrored queues.
Queues _reside_ on the node to which the client was connected when the
client created the queue initially. The queue is addressable from any
node within the cluster, both from a publishing and consuming pov.
