I'm not sure if/what your joking about, but I sure wouldn't trust
inverse delegations to be correct, with companies out on the net
deleting delegations in excess of their real authority.  Of course
if you did this at least you wouldn't have to worry about be routing
addresses where the's wern't correctly delegated...

The question with regard to trusted agencies is a real problem,
and apparently one of the ones that still hasn't been solved.
