Yes, this approach is impressive (you seem to have done it) and looks to be quite doable by a human with the skill and time to do it. We would need to see a report on if/how a machine (some p4p server) can do it.
Will the p2p folks be comfortable depending on such a smart servers developed for and owned by ISPs? And if the p4p server is not owned by ISPs, who will pay for it? Last but not least, is bandwidth not really much simpler and cheaper given the 100s of fibers in a cable and 100s of wavelengths in each fiber running 40-100 Gb/s?
