ISP's have been very clear that they regard their network maps as being proprietary for many good reasons. The approach that P4P takes is to have an intermediate server (which we call an iTracker) that processes the network maps and provides abstracted guidance (lists of IP prefixes and

Won't this approach (using a ISP-managed intermediate) ultimately end up being co-opted by the lawyers for the various industry interest groups and thus be ignored by the p2p users? To bring this back to network operations, it doesn't much matter what lawyers and end users do. The bottom

Or, everybody can put their heads together, make something that works for ISPs operationally, and give the end users faster downloads. The whole question is how to multicast content over the Internet in the most cost effective way. This will work as long as the optimization strategy is

I would certainly view the two strategies (reverse engineering network information and getting ISP-provided network information) as being complimentary. As you point out, for any ISP that doesn't provide network data, we're better off figuring out what we can to be smarter than 'random'. So
