I'm not talking about any of these levels. I'm talking about the reuse 
of the RTP session's 5-tuple for the DTLS/SRTP 5-tuple, as described in 
RFC 5764 section 5.1.2.

I said the same thing earlier on this thread (Nov 5), when you first 
responded (thanks for being the first responder!)

You do make the point that the term "multiplex" is so over-used, it 
should probably be abandoned altogether - but that section talks about 
(de)multiplexing, so changing terminology is probably too late for that 
particular usage.
