Currently broadcasting actor boradcast messages by calling 4 tell() calls, which is identical to broadcasting. But in Akka next version (currently mentioned as akka-2.3.0-RC1) has freedom of creating BroadcastGroup. We tried but it was impossible with current Play-Framework (v 2.2.1), since it didn't support that Akka version. It would be great to incorporate new Play Framework with new Akka version, to enable using BroadcastingGroup.
