Thanks for the help Alexis but the scenario is a little more complicated... I think exchange binding is the only way to go... but I'm open for suggestions ;)

Users are able to log-on to the system using more than one device at the same time (mobile, web, desktop) and it is a requirement that messages are delivered to each of these devices even if they are all logged on at the same time. Sooo... I am looking at exchange binding like:

P -> Topic Exchange <------------User1Exchange 
|_________temporary Q mobile
|________temporary Q web
|_________temporary Q desktop 

Functional Requirements:
Topic exchanges 
Messages published to exchange while user offline are available when user logs-on
One "permanent address" per user (thought of queue - looks like I need exchange)
multiple instances of the same user logged-on concurrently

Have you tried using direct exchanges?
