Is there a possible revenue stream here for larger ISP's to begin
charging their customers for not aggregating, and creating a penalty fee
for each borken route? We're running out of IPv4 space (and I don't
think this can be solved with IPv4). We're running out of routes for
the Cisco Sup2 engine (among others), but unless someone makes money on
it, this won't be solved.
