 // P2PSocketDispatcher is a per-renderer object that dispatchers all
 // P2P messages received from the browser and relays all P2P messages
 // sent to the browser. P2PSocketClient instances register themselves
 // with the dispatcher using RegisterClient() and UnregisterClient().
 //
 // Relationship of classes.
