Hi Alex,

Sorry for the delay in addressing this. I hope it's still relevant.

That's strange. Given a RabbitMQ/XMPP node running at 
rabbit.my.host.edu, try communicating with the JID "rabbit.my.host.edu" 
(i.e. without a node or resource part, a bare domain JID). Send it a 
message with just the word "list" in it, and it should send back a list 
of the exchanges it knows about. "list exchangename" should give you a 
list of bindings. Also, when adding a buddy to your buddy-list, if you 
become friends with "exchange at host/binding.pattern.#", the resource part 
is used in the queue.bind command. Similarly, when messages are 
delivered to you, the resource part of the from address is the 
routing-key from the message's publication.

You can't log in as those JIDs. They're virtual, owned and controlled by 
the gateway code. Think of them as relay bots that are distant from you 
in the network. Your applications (endpoints) will have to have their 
own local JIDs, which when bound to remote exchange-JIDs will have 
proxy/relay queues created for them.

Cheers,
