All you need for remote recording is the ability for the javascript to create a separate media stream to the recorder (SRS), as if the SRS were a third participant, and fork the user's audio/video into both streams.  The 4.2.7 requirement implies that will be possible.

Correct.

And I believe that enabling browsers to do that would be a very bad 
idea. That is specifically why the requirement for recording should be 
careful to explain the difference between these two and why one might be 
acceptable while the other not.
