1) I'm not sure what you mean by rabbitmq-erlang, but yes, you should 
avoid clustering over a WAN. ATM this means the shovel is the best solution.

2) The queue only exists on one node in the cluster, but you can access 
it from any node as if it were local.

That's correct, although it's more a consequence of (2).
