+ * technical restriction on which type of master channel is
+ * used as the transport.

+ * This channel object is currently only capable of running as
+ * a websocket server and is a pretty crude implementation
+ * of it, not supporting the full websockets protocol feature
+ * set. It is sufficient to use with a simple websockets
+ * client for encapsulating VNC for noVNC in-browser client.
