Sorry for the late response, but I got some numbers in Japan.
(1) httpd access logs of www.kame.net
In 24-hour access logs on September 13, there are 148 unique IPv6
addresses within 1,849 unique IPv4 and IPv6 addresses.
So, about 8.0% is IPv6.
The breakdown of IPv6 address blocks:
2001::/16 127
2002::/16 9
2400:2000::/19 1
3ffe::/16 11
If we remove 528 addresses from Yahoo! Slurp and Googlebot, the IPv6
ratio becomes 11.2%.
Obviously, this site is biased for IPv6 users but Jordi's number isn't
far off.
(2) traffic growth at an experimental IPv6-only IX in Tokyo
We have updated the traffic graph of NSPIXP6 at
http://www.wide.ad.jp/nspixp6/traffic.html
The traffic volume of IPv6 is still about 1/1000 of IPv4.
The IPv6 growth rate has slowed down a bit for the last 12 months.
