According to RFC 5969 for 6rd:
" Embedding less than the full 32 bits of a CE
IPv4 address is possible
only when an aggregated block of IPv4
addresses is available for a
given 6rd domain. This may
not be practical with global IPv4
addresses, but is quite likely
in a deployment where private
addresses are being assigned to
CEs. "
So the /64
limitation for 6rd applies when an aggregated block of IPv4 addresses is not
being used.

I fail to find this email, could
you provide archive pointers or explain
again?
I'm not aware of any
instrinct /64 limitation of 6RD, and existing
implementations prove the
contrary.
