Šand let each RTP packet be associated with one, and only one, of those
MIDs/m-lines.


You can then have application logic saying e.g. ³If no Œloudest-speaker¹
media is received, then duplicate the Œboss¹ media on the screen
associated with the loudest speaker². It¹s much more flexible, and without
any of the constraints mentioned earlier.
