There are two meanings, in BGP operations, of "peer." One is simply 
establishing the BGP connection.  The second is an economic one, in 
which the two parties agree they have comparable numbers of 
customers, and it is in their mutual interest to exchange their 
customer routes -- NOT full Internet routes.

It's getting harder and harder to peer with national providers unless 
you are also a national or substantial regional provider.  At a 
minimum, most bilateral peering arrangements expect both sides to 
have 24/7/365 NOCs, a national or regional backbone of at least DS3 
and preferably faster, and a substantial customer base.  There are no 
enterprises at the major exchange points, although some of the large 
hosting centers are almost exchange points in their own rights.

If you don't qualify for peering, you need to buy transit from one or 
more providers.

One exception is the growth of local exchange points, which I happen 
to think are very beneficial.  The first generally known local 
exchange started in Tucson, AZ.  In a local exchange, local providers 
and significant enterprises share either a small switch or a 
distributed layer 2 subnet, and have a small router or route server 
that does peering on behalf of the local organizations.  By using a 
local exchange, you can actually go across town rather than being 
backhauled across half a continent to go between major provides.
