I'm not qualified to debate procedural issues, but I will say that, from a distance, this does smell like a kill-what-we-don't-like. As you have undoubtedly felt the irony of me defending Keith on this kind of issue, I will confess that there is a little part of me that did not mind a bit seeing him getting a taste of his own food in that matter, but I still think this is premature. > but the real point is that it's now time for the > reluctant ISPs to get their heads out of the sand. I don't think making 6-to-4 historic will change anything in that regard, which is why I said above that it did look like a kill-what-we-don't-like. > You're correct that some ISPs will try to get monopoly > rents out of the IPv4 shortage, and use CGN to capture > customers in walled gardens, but fortunately capitalism > provides a solution to such misbehaviour: other ISPs can > deploy IPv6 as a competitive advantage. It does not matter, as long as the core of the "haves" don't do anything about it, as they command a big enough market share. Besides, you have not convinced me and not many ISPs either. I understand what you are trying to do here; nevertheless, 1Pv6 has not reached critical mass; although I do understand the "disable 1Pv6" issue (probably better than most) and I do indeed recognize that some of the brokenness comes from 6to4, it does not change the fact that deprecating 6to4 will reduce the sub-critical mass before it starts chain reaction, if it ever does.
