Ahhh ... you are right, I don't need queues to be exclusive (They were made default without me giving too much thought to it).  And better yet, without making queues exclusive, the auto-deleting issues since to be going away.  Thanks for the help!

If so, surely having the queues exclusively owned would prevent clients from moving between f/e servers. You may want to look at the "queue leases" feature (http://www.rabbitmq.com/extensions.html#queue-leases).
