I am using Anycast 6to4 at home and it worksforme(tm). Who is going to be my
6RD endpoint when 6to4 is deprecated? My ISP does not provide 6RD. I don't
know if ny DOCSIS modem is compatible with 6RD, and I know for sure that my
CPE does not implement 6RD.
6RD is NOT an alternative to 6to4. 6RD is an alternative to native IPv6 for
access networks. To put it another way, 6to4 is deployed by end sites, whereas
6RD is deployed by access providers.
Also IMHO, splitting the IPv6 Internet is a worse idea than keeping 6to4.

I do not believe we can update the millions of RFC3484-capable nodes in the
wold, in the expected time frame for 6to4.
