The iTrackers just helps the nodes to talk to each other in a more efficient way, all the iTracker does is talk to another p2p tracker and is used for network topology, has no caching or file information or user information..
After reading the P4P paper, it seems like the iTrackers have some large implications. Off the top of my head: - - The paper says, "An iTracker provides... network status/ topology..." doesn't it seem like you wouldn't want to send this to P2P clients? Is the "PID" supposed to preserve privacy here? I have some doubts about how well the PID helps after exposing ASN and LOC. - - As a P2P developer, wouldn't I be worried about giving the iTracker the ability to tell my clients that their upload/download capacity is 0 (or just above)? It seems like iTrackers are allowed to control P2P clients completely w/ this recommendation, right? That would be very useful for an ISP, but a very dangerous DoS vector to clients. These are just a couple of the thoughts that I had while reading. Eric

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 percentages) to the p2p networks that allows them to figure out which peers are near each other. The iTracker can be run by the ISP or by a trusted third party, as the ISP prefers.
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?

This idea is what I am concerned about. Until the whole copyright mess gets sorted out, wouldn't these iTracker supernodes be a goldmine of logs for copyright lawyers? They would have a great deal of information about what exactly is being transferred, by whom and for how long.
