I believe that the optimal configuration would actually involve only
one routing entity and no peering at all.   I'm pleased that instead 
we've implemented a model which (while not optimal) allows for a 
growing Internet service provider industry.   Solutions which are
optimal under one constraint tend to degenerate in the real world.

Shortest-exit routing and equivalent distributed peering is used to 
avoid settlements for transit costs.   If there's a strong demand 
for dissimiliar peering, then it's likely to appear with settlements.
