  This is good.  I would like to see this expanded to cover integrity
  as well as confidentiality.

omment:

The document says:
   
  Note that the appropriate mechanism to ensure confidentiality and
  integrity of RTP packets and their payloads is very dependent on the
  application and on the transport and signaling protocols employed.
  Thus, although SRTP is given as an example above, other possible
  choices exist.
   

This would be more useful with a pointer to at least one other example
and/or a discussion of the application issues which vary the means by
which confidentiality and integrity are assured.
