It's a pure API-related property to help the developer identify a particular DataChannel object if several objects (with the same transport porperties) are used.

Yes, it's not intended to be some "channel id" on the wire, but
it would have to be transported to the other end so that the 
corresponding DataChannel object on the B-side can be initialized with 
the same label.
