Presumably you(pl.) are aware of the following 2 drafts, which are in 
WGLC now, and seem likely to be adopted (at least in some form):

http://tools.ietf.org/html/draft-ietf-v6ops-6to4-advisory
http://tools.ietf.org/html/draft-ietf-v6ops-6to4-to-historic

At minimum one would hope that you're heeding the warnings in the first. 
Another view (one that I personally hold) is that any effort you might 
be putting into making 6to4 work better would be better placed in 
deploying real IPv6 instead; and that the world would be a better place 
generally if all of the so-called "transition mechanisms" just went away.
