The value is that it exposes IETF-goers who don't normally run IPv6- 
only to this type of network configuration. At the very least this  
forces people to formulate their objections to this treatment, which  
may give us valuable information in and of its own, and hopefully, it  
will show one or more of the following:

- how easy it is to run IPv6
- where the problem areas are with running IPv6
- what still needs to be done in standards, implementation and operation

There was a suggestion to rate limit IPv4 or NAT it heavily rather  
than turn it off. That completely misses the point. As long as there  
is IPv4, you don't see what's missing from IPv6.

Another suggestion was to charge more for IPv4. I love that idea. Give  
everyone who only needs IPv6 access a discount on the meeting fee.  :-)

But I think what we really need is to get some people together to  
define the parameters of this experiment and to work out what's needed  
to prepare for it.

In the mean time, I'm interested to hear about jabber clients that can  
work in an IPv6-only environment (even though jabber.ietf.org doesn't  
have an IPv6 address).
