A similar thing occurs in Australia and I recently parsed the CSV file
published by the ACMA of all prefixes it is authorised to allocate or
has been allocated and its a horrible mess of sorts. So I can see how
this might be useful especially for keeping up with changes globally to
the benefit of all but without everyone needing to keep local databases
or updating their own databases themselves.

I'm not exactly clear on when DNS queries should be triggered, or how
many need to be requested either or if these would interfere with
existing wild card entries.

I don't have time this morning to test but I like the idea a lot and I
very much would like to see it or some variation of it work.
