(As SIP WG cochair)

As Dean already said, we spend 3 hours last night trying to plan a 2 1/2
hour session based on input we do not completely have. We don't think we
finished, but this was the best we could reach so far in the time
available. Things can move up, but they don't solve the fundamental
problem that we don't have enough time. It was not our idea to limit SIP
to a single session - this was forced on us by the ADs.

Modification of this agenda is more likely to occur not by complaining
about the time allocated, but by the presence of technical discussion on
list over the next 8 days.

Some generals:

We have taken the principle that if discussion time is needed on
chartered items specifically, then they come first, and more
specifically highest priority for any discussion needed to get something
out of WGLC and into publication request. This is then followed by
documents that we envisaged could hold up chartered items (in this and
other groups) if not discussed. Then follow the other items where time
has been requested.

Some specifics based on comments received so far:

Domain-certs and eku are in WGLC which ends of Friday next week. These
are a dependency from other chartered items where we are ready to submit
the publication request. We will not have a view of what specifically
needs discussion on these in the meeting until the end of the WGLC, when
all the comments are in. Many of the comments made will not need
discussion in the SIP session and can be discussed on list by the
editors after the end of last call. If any comment does need SIP WG
session time, then we will give it on the above basis.

Outbound is in WGLC and has no time. We are still waiting for input to
know if it needs time - not helped by the authors dropping yet another
new version in the inbox 3 minutes before the -xx deadline when it
should have been there a month ago. Our current view is to issue a
refreshed WGLC on this following the meeting but that can change.

Location conveyance is in WGLC and has no time. Again author drops new
version in inbox 3 minutes before -xx document deadline. This document
is impacted by:

http://www.ietf.org/internet-drafts/draft-peterson-geopriv-retransmissio
n-00.txt

Which will be discussed in the GEOPRIV group, but if followed reverses
the decision we made in the location-conveyance breakout at the last
meeting. We hope the GEOPRIV discussion does not force rediscussion in
SIP, but please bear in mind that it could do so.

RPH in responses is not chartered. 2 meetings back the WG expressed a
wish to work on this. The AD pushed back to our request to charter. As
the AD makes the decision, it is not chartered and has no milestones.
That's why we had the further discussion in the last meeting - where
again we came to no conclusions, and I assume the AD is still
unconvinced. Fundamental problem - convince the AD. Put him in a corner
somewhere in Philadelphia and kick hell out of him, but we don't need
the SIP session to watch you do that - although it may be entertaining!

Media security requirements is holding up other chartered items in both
SIP and AVT. When we considered this for inclusion, we believed there
were two items that may need agenda item. Overnight Dean seems to have
taken the time away at the moment, but I remain unconvinced that this
does not need time.

This is the media-security requirements milestones:

Sep 2007    Requirements for media keying to WGLC (Informational)  
Nov 2007    Requirements for media keying to IESG (Informational)  

Which provides the requirements for the mechanism in these charter items
in SIP.

Dec 2007    Establishment of secure media sessions using DTLS-SRTP to
WGLC (PS)  
Feb 2008    Establishment of secure media sessions using DTLS-SRTP to
IESG (PS)  

And these chartered items in AVT:

Dec 2007    Submit in band keying mechanism for SRTP draft for Proposed
Standard
