Oh, I understand the issues just fine. It's DJB who clearly demonstrates he doesn't understand the issues. His argument derails in the second paragraph, where he appears to go by the assumption that at some point we flip a switch (he calls it "the magic moment") to go from ipv4 to ipv6. ipv6 was designed with the idea of it running alongside ipv4 and in fact all mainstream operatings systems and enterprise networking equipment are perfectly capable of this right now. Yes, transition will be messy in the upcoming few years, but that is for the most part not because of poor design choices in ipv6. That is caused by almost everyone worldwide putting their fingers in their ears and singing lalalalalala whenever the topic is brought up (some think NAT is the solution, others say we should just force some of the holders of /8 blocks to give those up). Had everyone gotten their acts together 5 years ago, we would be visiting most websites over ipv6 by now.

I'm amazed at how much misinformation and outright bullshit someone can put into one single webpage...

Actually, from what I've read, the Hurricane tunnel (http://tunnelbroker.net) gave someone their full 100mbps through the tunnel.

You clearly haven't worked with Fx3 yet. At first I was skeptical about the new smart bookmarks and address bar, but now that I've used it for a month or two (starting with beta 2) I'm quite pleased with it. The address bar basically does exactly the same as it always has, except now it actually does an on the fly substring search in your history instead of just giving an arbitrarily sorted list of previously visited sites. I would dare say this is one of the biggest improvements to the web browsing experience in the last several years.
