Hi,
To the basic question of the IPv4 outage -- preparations are
indeed underway, to implement it as Russ described on 12/22/2007[1].
Early next week, there will be a wiki page accessible specifically
for our event, providing more detail and more pointers. In the
meantime, if you have specific comments, you can send comments to
the team Russ set up[2].
In the meantime, NANOG and APRICOT have had similar events. You
can see some of the data captured here:

and some writeups:

Following the mail list discussion, we have considered several different
configurations for achieving the desired network experiment environment.
It is important that everyone have adequate opportunity for advance
configuration, and it is important that severe impact on other network
resources at the meeting venue be avoided. With these goals in mind, we
intend to add an additional IPv6-only subnet, with a different SSID on
the wireless network. The SSID will include some clever name that
includes the string "v6ONLY". This SSID will be available on all the
wireless access points throughout the venue for the entire week.
Everyone is encouraged to try using this network well before the plenary
session. Neighbors and friends are encouraged to help each other debug
problems, and the kind folks at the help desk in the Terminal Room will
also be happy to assist with any configuration challenges, IPv6-related
or otherwise.

What's going on with the preparations to turn off IPv4 at IETF-71?
It's been really quiet surrounding that topic since the initial
discussion.
Because I've had an IPv6 mail server for years and a WWW proxy that
allows IPv6-only hosts to get access to the IPv4 web is fairly trivial
to set up (tip for XP users: XP can't do DNS lookups over IPv6, use
Firefox and configure it with the IPv6 address of the proxy), my
preperation for this has been mostly getting Jabber to work over IPv6.
A while ago I managed to find a public Jabber server that is reachable
over IPv6 (amessage.de with some other domains pointing to the same
server). Unfortunately, the client I generally use, Apple's iChat,
does support Jabber over IPv6 when there is IPv4 connectivity, but
when the system has no IPv4 address it says that "you're not connected
to the internet" and doesn't try to connect over IPv6. Recently I
thought this was fixed but it turned out that the Parallels Desktop
virtualization enviroment sets up a bunch of virtual interfaces with
private addresses, which is enough for iChat to work over IPv6.
Anyway, I started looking for Jabber clients that support IPv6. Most
don't, but there are so many Jabber clients that there is actually a
choice of ones that do. Unfortunately, none of them could connect to
the jabber.ietf.org rooms. I first thought this was because of the
clients, so I didn't keep a list of clients that support IPv6. But it
turned out that this is a problem with my iljitsch at amessage.nl
account on the amessage.de server, which doesn't seem IPv6-related.
So... does anyone know a place to obtain a Jabber account that's
usable over IPv6? I assumed psg.com would be a good candidate, but
even though psg.com has a AAAA record, jabber.psg.com doesn't.
