Something building on this perhaps?

class SerializedActorRef(val uuid: Uuid,
val classOrServiceName: String,
val actorClassName: String,
val hostname: String,
val port: Int,
val timeout: Long) extends java.io.Serializable {
import java.io.ObjectStreamException

@throws(classOf[ObjectStreamException])

def readResolve(): AnyRef = {
val address = Actor.remote.address
if ((hostname == address.getAddress.getHostAddress || hostname == address.getHostName) && port == address.getPort) {
val actorOrNull = Actor.remote.findActorByIdOrUuid(classOrServiceName, uuid.toString)
if ( actorOrNull eq null) Actor.registry.actorFor(uuid).getOrElse(null) else actorOrNull
} else {
RemoteActorRef(classOrServiceName, actorClassname, hostname, port, timeout, None)
}
}
}

Postponing this to 1.2
