>        Common Local Transmit and Receive Ports (Symmetric RTP)

  I have never heard the term "common local port" before reading this
  document, and I don't think it accurately describes the concept of
  using the same port pair for both directions of a bidirectional
  communication.

Section 5., paragraph 1:
>    There is no additional security exposure if a host uses symmetric RTP
>    or symmetric RTCP.

  DISCUSS: I don't think this is true. If both directions of a
  communication use the same port pair, it becomes easier for an
  attacker to locate the reverse flow for a given flow instance.
  Especially when the host would otherwise use randomized ports.

Considering the write-up:

Note to RFC Editor

  The IESG thinks that this work is related to IETF work done in the WGs
  AVT and BEHAVE, but this does not prevent publishing.

And two ADs balloting a 'YES', would it not be better to make this an
AD sponsored individual submission (or is it AD sponsored independent submission ;-)) as there apparently is plenty of IETF support for this
document ?
