Absolutely, assuming UUnet were willing to peer with you, and at that
rate for route exchange. Terms to be negotiated in the free market.
In that case, we already have the system in place. It just turns out
that the negotiated rate per prefix is $0.
Or 'not at any price' in the case of refused peerings. Or at $$$
in the case of paid for peerings. And with no distinction drawn
between length/usefulness/CIDRity of prefixes. However, it has
been suggested that the ternary nature of this relationship
is insufficiently granular for people to exchange the routes
they want.
