However, if there was a reasonable translation mechanism available which allowed IPv6-only end systems to access IPv4-only content, I think the picture would look quite different.
Doesn't deploying a 6to4 relay in the content provider network, along with IPv6 access to the content provider network, exactly meet this requirement?
No. An end system who only has IPv6 addresses has no way to access IPv4-only content, regardless of whether the IPv6 address is constructed within 2002::/16. (and it's a bit of a stretch to imagine an end-system that has IPv4 close enough for a 6to4 prefix to be constructed, but far enough away for it not also to have an IPv4 address) Joe
