you mean aside from the ipv6 forum mailing list?  [ note that ipv6 forum
members do not actually run ipv6, they just think other people should. ]

the stats i am seeing, and they are not really great measurements, but
they're what we have, are coming up on 1% ipv6 traffic.  and this is
pretty much the same asia, europe, and north america, with less down south.

actally, drc, here is where you and i diverge.  there will never be
demand for ipv6 from the end user.  they just want their mtv, and do not
care if it comes on ipv4, ipv6, or donkey-back.

it is we operators, and the enterprise base, which will feel the ipv4
squeeze and need to seek alternatives.  and, imiho, ipv6 is the
preferable alternative we have today.  and it is we the operators who
get to make it deployable so that the customers will not have to care
how their mtv is delivered.

and the chicks ain't free.
