	A big problem here is that ISPs differentiate themselves based on
who they buy bandwidth from. An ISP that has a T1 to CRL, say, benefits
greatly when a larger competitor gets a T1 to CRL as well, but the larger
competitor doesn't benefit if they already have multiple T1s and T3s to
the larger backbones themselves. A better idea is a miniature NAP for the
ISPs in each large metropolitan area for exchanging local traffic.
