It is possible that a broken 6to4 relay somewhere was causing problems.
Running your own local 6to4 relay (rfc3068) will improve performance and
reduce the chances of going through a broken one.

FWIW, I have been running some AAAA records for almost a year on some
revenue generating sites without any reachability complaints or
drop in traffic.   I do run a local 6to4 relay though.

It sounds like you are an existing ISP in the ARIN reigon. If so then 
you qualify for a /32 allocation.  Let us know if you have any problems 
getting one.  For non-ISP's, the policy is still being worked out.  See 
the ARIN ppml list for discussion.  As for deaggregation, it is not
recommended because some filter (/48's) and some don't which results
in sub-optimal paths, but it can be done depending on what your
peers will accept.
