Ah, right.

So the shovel does not handle clusters specially at all; if you 
configure the shovel on two cluster nodes you will get two shovels 
running in parallel. Each message will go through one shovel or the 
other, but the order will get mixed up.

Federation is different; in a cluster each federation link will only 
exist once. I wonder if the shovel should be more like federation in 
this regard...
