No, we are graduate students in computer science, my research interest is distributed computing system. we want to push P2P systems, not restrict it. P2P systems are promising because they require no centrailized servers and no precise control over network topology or data placement. however, the flooding-based query algo. does not scale, because it generates a large amount of traffic and large systems will quickly become overwhelmed by the query-induced load. our goal is to to study new algo. for efficent searching and indexing in P2P systems.
