Nope. In a given reasonably sized (.i.e a city or so) geographical area, you'd be lucky to get better than 20% locality of your traffic. There are some exceptions where there are major traffic sources in the area, but those tend to be pretty concentrated. The percentage decreases further when you take into account traffic to/from NSPs' customers in the locality as the NSPs are not likely to private peer with local providers. This is in no way a case against local peering, (every bit less traffic dumped into the core from every locality adds up) but one needs to be aware of what is gained from "exchange in every town" scenario. -dorian
