This is happening already, and it pushes one of my buttons _really_

The geographic locality of reference of the current Internet is
pathetic.  When my telnet session from St Pete to Tampa, Florida, goes
via MAE-East, or worse, MAE-_West_, there's something _seriously_

It's my analysis that the problem is that small (T-1 and below)
customers should be buying their connectivity from (and there should
_be_, for them to buy it from) a local exchange-type provider.  IE: buy
a T-3 up hill to, oh, say, the top 6 or 10 backbones, and then sell
transit to local ISPs and IAPs in your geographic area.

This doesn't seem to be technically difficult, and it seems like it
ought to be pretty easy to sell... sure, you're one hop further from
the backbone... but you're now two hops away from _10_.

Sane?  I should be looking for capital?  :-)

Are there any major potholes in this theory that I'm missing?
