In any case, content providers can avoid the confusion if they simply put up a local 6to4 router alongside their 2001:: prefix, and populate DNS with both. Longest match will cause 2001:: connected systems to chose that dst, while 6to4 connected systems will chose 2002:: as the dst. There is no need
Huh? Longest match done by web browsers and other applications? Since when?
It's been part of GNU libc for a while, but it has been disabled by several distributions. Usually, random selection leads to better results. At they very least, it makes renumbering much simpler because all addresses are equal, independently of where your clients are located. It's been a PITA to get this resolved (both in the IETF and in implementations), and it's still not done AFAIK.
