As mentioned last week -- the wiki is now accessible:

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  

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 ( 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 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  
account on the 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 would be a good candidate, but  
even though has a AAAA record, doesn't.
