Well, those are the options you have. Either you care about the messages 
in the queue being available at all times, in which case you need 
mirroring, or you care about them surviving restarts but not node 
failures, in which case you need a durable unmirrored queue, or you 
don't care at all, in which case you can use a transient queue.

I'm not sure what other options could exist?
