title: Select remote actor on random port
body: <p>In Scala, if I register a remote actor using alive(0), the actor is registered at a random port.
  I can do the registration like this: register('fooParActor, self) in the act method.</p>
  
  <p>Now, on the master/server side, I can select an actor by supplying the port. Do I need to manually scan the ports in order to use random ports? </p>
  
  <p>The problem I am trying to solve is to create n actors on a node and then select them all at a master/server program, e.g. start 10 slaves on node x and get a list 10 remote actors at node y.</p>
  
  <p>How is this done?</p>
