Hi,

This version contains the following changes:

   o  Aligned with recent changes in draft-ietf-mmusic-rid and draft-
      ietf-avtext-rid.

   o  Modified the SDP offer/answer section to follow the generally
      accepted structure, also adding a brief text on modifying the
      session that is aligned with draft-ietf-mmusic-rid.

   o  Improved text around simulcast stream identification (as opposed
      to the simulcast stream itself) to consistently use the acronym
      SCID and defined that in the Terminology section.

   o  Changed references for RTP-level pause/resume and VP8 payload
      format that are now published as RFC.

   o  Improved IANA registration text.

   o  Removed unused reference to draft-ietf-payload-flexible-fec-
      scheme.

   o  Editorial improvements and corrections.

I don't think there are any other changes needed at the moment and believe the draft is ready for WGLC.

Cheers,
Bo (as individual)

> Abstract:
>    In some application scenarios it may be desirable to send multiple
>    differently encoded versions of the same media source in different
>    RTP streams.  This is called simulcast.  This document describes how
>    to accomplish simulcast in RTP and how to signal it in SDP.  The
>    described solution uses an RTP/RTCP identification method to identify
>    RTP streams belonging to the same media source, and makes an
>    extension to SDP to relate those RTP streams as being different
>    simulcast formats of that media source.  The SDP extension consists
>    of a new media level SDP attribute that expresses capability to send
>    and/or receive simulcast RTP streams.
