Sorry for the aside, but I hope the neveragain.de author will make a blog post about their site theme. I _really_ like it, and of course I would like to mostly copy it for my own personal site.

I would argue that the IPv6 sales story is unmemorable|unclear|weak. Also, it is arguable that most IPv4 addresses are wasted.
