What you may want instead is the staticallyIncludedDestinations  
feature. You could also use startup destinations.

In either case it won't match what you want since you're using  
queues. If you really want both A's consumers and B's consumers to  
receive the same set of messages, then you'll need to use a topic,  
and perhaps something like virtual destinations to bridge to a queue  
at each broker. Otherwise queue semantics hold even across the network.

It sounds like you may want to try out the master/slave feature  
instead if you care about both 0 message loss during failure and that  
a message must be consumed once and only once.
