I remember seeing similar, startling, statistics at the first bsdcans'
KAME talk. glad to see that the progression has not changed at least ;)
did he talk about any of side effects of an ipv6 world...i remember
thinking about living in a world w/o NAT and getting pretty excited...

wow - that's pretty wicked. so if i understand ipv6 correctly (which i
most likely do not) you get a publicly routable IPv6 addr from these wifi
hotspots right. hmm...now i can see why there has been some pushback, or
inaction at least, from many western IT vendors. i surprised that OSX had
problems getting things going...i always suspected that the paradigm shift
would be under the surface of the os - not on the user end.

well, i'd assume that most backbone carriers use a standards based
architecture. i mean that's one reason standards are published right, so
high capacity carriers can interact and not have to reinvent the wheel
right? it's not like the verizon is using decnet while quest is using IP
on their backbones - shoot maybe they are, that'd explain a lot ;)

yea it's pretty awesome for sure. one thing that's really suprised me is
how much BSD code i've run into when working with various storage vendors
- we are everywhere :)
