this figure seems to be completely over the top. i would be interested in
seeing those 'measurements', an explanation of why they are statistically
representative and the method of extrapolation. perhaps it was a typo and,
instead of 'extrapolation', they really meant 'exaggeration'? that would
make more sense ;]

please define incredible using a non-subjective measurement system -
absolute counts and percentages of total traffic will do. as stated above, i
would likewise be interested in knowing how representative your traffic is
of general internet usage. as an example, i would expect web servers for an
incredibly popular site discussing v6 to have a disproportionate amount of
v6 traffic.

i don't like guessing, but if i were pressed, drunk or otherwise
intoxicated, i'd say default support in client software is not the single
bottleneck - being able to purchase v6 transit and have your v6 work as well
as your v4 is another one that you can't really get around. i'm not up to
date on these things, has someone figured out how we're multihoming with v6
yet and, more importantly, got vendors to agree on and implement it?
