Won't current Windows clients work just fine in this case?

I have no idea what a fix should look like for some of the non-Windows

No, unfortunately broken 6to4 auto-configuration (ie, in Vista, XPSP2, when on a non-RFC1918 IP address) breaks, and you get 90s timeouts before falling back to IPv4/A.

This must be a broken RFC 3484 implementation:
- 6to4 should be less prerefed than IPv4 if the service has both AAAA and A record.
