 While this would perhaps increase the 'possibility' of aggregation
 increase, it ignores the fact that networks are laid out w/ wires
 and planned logically wrt tariff issues and existing infrastructure
 and capacity.

I don't see that this is relevant.  If I call PacBell in San Jose,
it's a 408 number.  In San Francisco, it's a 415 number.  What does
this have to do with wires etc?  The point is that every telephone
company knows where 408 is and how to route traffic to it.
