Changing the subject, since we're touching on a different topic...

Hmm..... this illustrates the fact that there are multiple reasons a 
track shows no data, and we may need to keep them straight, because they 
affect what might happen next:

- the sender is not sending data, but may do so in the future (source muted)
- the recipient has asked not to receive data, but may ask for it later 
(I was using "muted" above for this, it may not be the best word)
- the sender has ended the stream, and no data will ever come again (ended)
- something in the middle prevents the delivery of data (which may be 
seen as "sender mute" on one side and "receiver mute" on the other, or 
may be a third state).

These may need to apply to a track or a stream (probably affecting the 
state of tracks).

Did I miss some variants?
