Refreshing
Both the article as well as the development. Although I'm very sceptical about the continuous "we're running out of IPv4, the Internet blows up tomorrow" (and nothing happens the day after) I still think it's a good thing that some companies (and projects) started paying serious attention to IPv6.
I'm somewhat proud to say that very soon all of my customer websites (and my own of course!) will be accessible using both protocols.
Either way, I think it's quite refreshing to read a story which shares both the strong and weak points of a new development. I was especially interested in your (author) display of interest in the possible potential. Because in my opinion a lot of Microsoft developments show high potential, in a lot of cases its poor marketing (and "after-sales") which turn it into a disaster.
