Currently LiftSession.sendCometActorMessage lets you send to a single actor of a given type, either one with no name or one with a specified name. It would be nice to have a version that sends to all actors by type. This is slightly different from LiftSession.findComet("Type").foreach(_ ! ), because sendCometActorMessage also sends messages to any comet actors created during this request cycle. It is this latter functionality that we are looking for, combined with sending existing actors of the type a message.
