RabbitMQ (and AMQP in general) don't support anything related
to 'presence'. From RabbitMQ point of view, user produces
messages, user consumes messages and that's more or less it.

Maintaining presence is (in my opinion) application specific,
and in most cases you should end up implementing roster
in your application.

In ideal world you could do that by just sending a message to yourself
when user connects and disconnects, however in practice that's
usually not so trivial.

In order to do this simple thing server-side Tony wrote a x-presence
exchange plugin some time ago. Here it is, I dusted it off a bit:

Take a look, and please do tell us if it helps to solve your particular problem.
