Again, 40-something percent of the IPv6 traffic that is observed on the net today uses 6to4.
Please point at the data behind that assertion. In many cases in the past, such assertions have comes from networks that do not have the hardware capabilities to monitor native IPv6 traffic. I remember one case at the RIPE meeting where someone from AMS-IX observed about one of these presentations, "I have more native IPv6 traffic on my exchange point than you have observed in the entire Internet. How is that possible?" Needless to say, that presentation did not go well.
Look at http://www.google.com/intl/en/ipv6/statistics/ That obviously does not see peer-to-peer traffic, but it does see IPv6 web clients, and just under 90% of those are native.
The evidence is that people are using it. You're trying to subject it to test cases that are largely meaningless - because in those cases IPv6 (of any kind) provides no marginal value in the near term.
So far, you have provided solid evidence that *you* use it, but not solid evidence that "people" are using it. Can you point to that evidence?
Almost all usage of IPv6 today is in spite of ISPs. For that matter, a great many successful IPv4 applications today are deployed in spite of ISPs. Again, ISPs in general have let us down, and 6to4 and Teredo are carrying ~90% of IPv6 traffic. ISPs are not in a good position to demand that 6to4 be deprecated.
Nope. As before, 90% of IPv6 is native, and it comes from a small number of large deployments. Maybe your ISP doesn't support it, but other ISPs do.
It's not one versus the other. 6to4 is helping to promote ubiquitous IPv6.
No, it is a barrier to ubiquitous IPv6 adoption.
