Allot seems to have been learnt by the community during the dog food  
tasting sessions, here is a small collection of the postings things  
learnt to date (collected by Ralph Droms in case you wondering which  
Slashdot: "<The Night the IETF Shut Off IPv4": IP Freely writes "At  
this year's Internet Engineering Task Force meeting in Philadelphia,  
conference organizers shut off IPv4 for an hour. Surprisingly, chaos  
did not ensue. After everyone got his or her system up and running,  
many people started looking for IPv6-reachable web sites, reporting  
those over Jabber instant messaging - which posed its own challenges  
in the IPv6 department. I was surprised at the number of sites and  
wide range of content available over IPv6. Apart from - obviously -  
IPv6-related sites; they ranged from 'largest Gregorian music  
collection in Internet' to 'hardcore torrents.' Virtually none of the  
better known web destinations were reachable over IPv6. That changed  
when ipv6.google.com (reachable only through IPv6) popped into  

(Ralph) I was at the IETF meeting and participated in the experiment.  
After manually configuring addresses for two IPv6-reachable DNS  
servers (for ideological reasons, Apple has not included a DHCPv6  
client with OS X), IPv6 "just worked" for me. I used Safari  
extensively throughout the experiment, and found there were more IPv6- 
reachable sites than I expected, but ipv6.google.com was the only  
major site I could access. Halfway through the experiment, we were  
given IPv6 addresses for access to gmail. I also participated in the  
experiment Jabber chat room, accessible through an IPv6-aware Jabber  
server set up by the IETF, through both Adium and iChat.

NANOG runs "IPv6 hour": an hour of IPv6-only networking on the  
conference network
IPv6 access to Internet can be made to work, but...
...there's just not a lot of native IPv6 content, yet
IPv6<->IPv6 translation is problematic (including Cisco NAT-PT)
Windows XP can be patched with an IPv6 stack but needs IPv4 for DNS
OS X requires manual config for DNS servers (no DHCPv6!)
