    A discussion on the dev list would at the very least leave those of us who 
don't subscribe out of the discussion . . .
    
    Our use case for virtual topics in ActiveMQ is fairly straightforward:  we 
want to be able to broadcast a message to an unknown number of different 
subscribers without doing something like camel multiplex on the application 
end.  The consumers must be able to do concurrent processing (multiple 
consumers) with queue semantics.  We need the consumers to be able to create 
and delete their own subscriptions without restarting the broker or doing any 
application configuration on our end; the consumers must be able to go offline 
and come back and find their messages waiting for them; waiting messages can't 
expire or be thrown away.  This probably has to be done with the latest 
ActiveMQ client library and without code changes.

> subscriptions as ActiveMQ itself does.
