It probably does lack one thing: a way of defining default policy for
addresses that don't have a user-level record.
DNS takes care of that with use of wilcards, i.e. you make a pointer to
<username>._user._policy.example.com
and enter
*._user._policy.example.com IN TXT "default policy record"
bob._user._policy.example.con IN TXT "Bob's policy record"
Thinking about it more - it may indeed be better to put "default" in
original policy record, because use of wildcards means it would be
positive caching on the ISP side, i.e. full default policy record
would likely be cached for every user which takes more memory then
caching of negative answer. But of course - ultimately both are bad
and non a solution for any large domain.
