if it is really a local-only exchange point, i.e. no one is using it for transit, and all are only exchanging local routes, lots of folk out here would be very interested in real measurements. like how much of an isp's traffic can they actually shed locally? not conjecture, real data.
Here in Utah, we have the UtahREP http://utah.rep.net with about 12 or so participants which are generally the largest local ISPs as well as the Utah Education Network. Soon Electric Lightwave and US West will be connecting to the UtahREP as well. Currently about 5%-15% of my traffic gets routed over the UtahREP. Of course the local gamers love it for the very low latency connection to all the Quake2 servers hosted by local UtahREP connected ISPs. Many of the ISPs connected to the UtahREP send newsfeeds to each other. Also, we have created an "UtahREP Caching Proxy Mesh" using ICP (Inter Cache Protocol) which is working quite well. I have about 95% participation rate from my dialup users (using a proxy autoconfig file), and I have just broken the 60% hit rate mark. Regional Exchange Points are an excellent idea.
