Rather than debate wheter someone in Aberdeen is really going to  
multihome to ISPs in Norwich and Belfast, let me observe that  
aggregating at the European national level is just fine. The largest  
countries in Europe each have about 1% of the world's population. So  
if they also have 1% of the routing table we can have 100 times as  
many routes as we could without geographical aggregation. That should  
give us plenty of breathing room.

It's harder for the US because there are no easy demarcations there.
