you can't specify an actor as a camel endpoint.

You can use ActorSelection to select multiple actors (even remote ones)
with a wildcard. However a wildcard in ActorSelection can only select all
actors at the specified depth.

This needs a benchmark to see if it would be a bottleneck or not. However
Akka Distributed PubSub uses optimization and sends a message over the wire
only once per node (if that node has a matching topic).

Another approach could be using a EventBus with custom classification
rules. However EvenBus is local ActorSystem only. You would need to
subscribe remote actors to the EventBus explicitly to carry messages from
one node to another.
