Well, the large ones that I know of that have done it already are using
dual-stack. I started to name names, but, I don't know for sure which
ones I am allowed to disclose at that level, so, I will not.

I know that it is public that Google is doing IPv4 and IPv6 dual stack
on the same infrastructure if your resolver is whitelisted.

However, it really doesn't matter whether they use dual-stack or other
mechanisms so long as an IPv6 client can reach the same content and
services via IPv6 that are available via IPv4.

My point is that the content and services need to be made available on
both protocols. It was not my intent to dictate specific means of getting there.

Finally, this word 6to4...It does not mean what you seem to think it means.
