------------------------------------------------------------

Yes, it gets a bit funky when you starting having the more complicated 
destination features in the mix.  For instance you can't create a durable 
subscription to a Virtual Topic like "VirtualTopic.FOO" because things get 
mixed up when you try to find you connection's previous subscriptions on 
reconnect due to all the name munging.

> MQTT clients that create durable subscriptions and that operate in a network 
> of Brokers can receive duplicate messages when they start failing back and 
> forth between brokers in the network.
> We should investigate using Virtual Destinations under the covers instead of 
> durable topics subscriptions as this is a known problem with the durable 
> topic case.  With Virtual Destinations the client would be subscribed to a 
> Queue that would receive all messages sent to the target Topic.
