How many of them are you planning on maintaining? May I quote you on this after you've been doing so for
a year and received 2 or three lovely FISA subpoenas for your LSN logs?

World IPv6 Day has only be going for a few hours, but things seem to be going fine, and it's our hope (currently) to keep www.xbox.com available over IPv6 indefinitely. I expect other participants will keep IPv6 enabled for some or all of their respective portfolios.
I agree with Lorenzo to a point, but...
Access will happen in due time by virtue of IPv4 runout. If content is available dual-stack ahead of that,
it dramatically reduces the need for (and load on) LSN. If it is not, then, LSN is going to be a much much
uglier situation to an extent that it might even have a catch-22 effect on IPv6 deployment in the

I don't think any of them are really waiting for that. However, I do think getting to that point is actually more
critical at this juncture than getting the eyeball networks fully deployed.
