title: can a lookup an akka actor address from configuration?
body: <p>When using Akka 2.0, Is there a way to get an ActorRef to a remote actor but have the address of the actor I am looking up come from configuration instead of specifying it programatically?  I want to, for instance use </p>
  
  <pre><code>AkkaSystem("mysystem").actorFor("akka://system@remotehost/user/whatever")
  </code></pre>
  
  <p>but I want to be able to change remotehost just by changing my
  application.conf.</p>
