- * During presentation session establishment, the sender expects the following

- * 1. |Init| is called to open a socket |mServerSocket| for data transport
- * channel.
- * 2. |NotifyConnected| of |nsIPresentationControlChannelListener| is called to
- * indicate the control channel is ready to use. Then send the offer to the
- * receiver via the control channel.
- * 3.1 |OnSocketAccepted| of |nsIServerSocketListener| is called to indicate the
- * data transport channel is connected. Then initialize |mTransport|.
- * 3.2 |NotifyTransportReady| of |nsIPresentationSessionTransportCallback| is
- * called.
- * 4. |OnAnswer| of |nsIPresentationControlChannelListener| is called to
- * indicate the receiver is ready. Close the control channel since it's no
- * longer needed.
- * 5. Once both step 3 and 4 are done, the presentation session is ready to use.
- * So notify the listener of CONNECTED state.
