Hmm. I suspect I would handle a problem like this architecturally, rather than at the individual Actor level. Remember that you don't usually have Actors connecting to each other by name -- instead, Actors usually provide ActorRefs to other Actors.
So I would probably have each service provide some sort of "gatekeeper" Actor, which mediates the provision of ActorRefs to the rest of the cluster, and only provide access to the systems that are appropriate to have it. The external services would have to go through this gatekeeper, allowing you to manage the process as tightly as you need. This approach does require that everyone play by the rules and not try to do an end-run around them. But if folks work within the system, it seems like a reasonably principled way to manage access...
