- * Implementation of PresentationControllingInfo
- *
- * During presentation session establishment, the sender expects the following
- * after trying to establish the control channel: (The order between step 3 and
- * 4 is not guaranteed.)
- * 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.

- * 1. |Observe| of |nsIObserver| is called with "presentation-receiver-launched".

- * 3. |OnOffer| of |nsIPresentationControlChannelListener| is called.
- * 4. Once both step 2 and 3 are done, establish the data transport channel and

- *    receives the answer.)
- * 5. |NotifyTransportReady| of |nsIPresentationSessionTransportCallback| is
