My article for Network World on Who's who in IPv6 was published a few days ago. It requires registration on their site but I hope you live through that to take a read. I might later be able to repost the full article on my blog but for now the only access is via Network World.
I am very much interested in feedback of who you felt I left off the list. I have some caveats, I was not able to do a who's who for service provider manufactures, professional services consulting, training/education, OS's/applications and security solutions. There just wasn't enough room. Perhaps I will get the chance to do that in another article.
