Seems like we *could* get a large part of the way there if people were
only checking the information in question.  While not the long-term fix
of being able to prove authorization to advertise space, simply requiring
a LOA at the edge, and requiring IRR further in, and keeping records of
what was advertised, would seem to be a worthwhile improvement on the
current state of affairs.  Total prevention is a very rough goal, so
making it more difficult, combined with being able to identify when 
someone did something bad, really ought to be a worthwhile interim goal,
and I've wondered for a long time why this isn't being done.

With 24 million small businesses in the US alone, that's way too many apples.
