Two more questions, then. Since it's Friday.

The peering graph ideally wants to map to the number space, and not to 
anything else. Suppose one organisation is able to terminate calls 
matching _+1650. and _+612. and _+1519. -- should that organisation be 
trying to peer three times, once per corresponding branch?

Bigger, nexus peers are going to be able to match a large range of 
numbers, but there are fewer of them. Smaller, itty-bitty enterprise 
peers are going to be able to match a much smaller range of numbers, 
but there will be potentially many more of them.

Is it more important for the big peers to connect to branches in the 
right place, or the smaller peers, in terms of scaling the system?
