Peer-to-peer architectures are very promising as a solution to general problems that arise in client/server architectures. That is, servers form a central point of failure, become performance bottleneck, lack scalability, and require powerful hardware systems causing economic burden. Peer-to-peer architectures help to solve these problems and they proved to be successful in domains like file sharing and distributed computing. We expect that a peer-to-peer system designed for CQs will outperform a traditional client/server based approach. PeerCQ system is expected to be highly scalable, self-organizing and support efficient and robust way of processing CQs.
