Grrr, I hate when I do that. I spent quite a bit of time on this post,
and the one time I remembered that I needed to go back and
double-check what I wrote there I wasn't at the keyboard. Thanks for
keeping me honest.

There was one other thing you wrote that I wanted to clarify, you
indicated that I was arguing for ISPs to only get one shot at an IPv6
allocation. Since my post was already really long I chose to leave out
the bit about how (TMK, which could be outdated) the RIRs are
reserving a bit or two for their allocations to ISPs so going back and
expanding should be an easy thing to do. On a personal note, I hope
that we DO need to expand IPv6 allocations to ISPs as this thing
finally gets deployed.

I'm not responding to the rest of your post because you and I have
already had those discussions in person on more than one occasion and
I know I'm not going to change your mind. I do think it's extremely
gracious of you to say that my post was "well reasoned" though. :)

Thanks to the others who had nice things to say as well.

Doug
