N.B. This FAQ focuses on the very nebulous term "p2p system". There's not a single answer that maps exactly to all peer-to-peer systems; this FAQ does its best to provide a general answer when possible, and provide concrete examples where it makes sense.Yes. It is rare to find a p2p service that does not scale. They are distributed systems by design, and most distributed systems are meant to scale. You could say, then, that many distributed systems take cues from p2p systems in order to scale properly. As a good example, Skype was built by the same engineers who built Kazaa, and Skype internally used p2p distribution in order to alleviate the load from any single node, and to save costs. Bittorrent also thrives in situations where there are a high number of peers.
