Yep.  There's no magic solution for that (Nimrod-style global link-state
_may_ help, but i'm not sure).

Well, the "small NAPs" are pretty much useless, as most traffic goes beyond
the geographical area served by a "small NAP";  and the "large NAPs"
can be in dozens, but _not_ hundreds or thousands.

The "NAP in every corner" is simply a manifestation of the rampant
cluelessness in regard to the global routing.

Well, AOL has its upstream provider in a different sense :)
