In the future we hope to have shovels that can be dynamically 
reconfigured at run time; I don't consider permanency to be an inherent 
feature of shovels. And being able to spin up a quick shovel to move 
messages from one queue to another within the same broker is a use case 
for that.

However, "permanent" shovels are all we've got at the moment. But bear 
in mind the shovel doesn't need to be in the same broker as the queues - 
you could spin up an ad hoc broker node on the same machine with 
whatever shovels you need, then shut it down when you're done.

Cheer, Simon
