// sfive - spreadspace streaming statistics suite is a generic
// statistic collection tool for streaming server infrastuctures.
// The system collects and stores meta data like number of views
// and throughput from a number of streaming servers and stores
// it in a global data store.
// The data acquisition is designed to be generic and extensible in
// order to support different streaming software.
// sfive also contains tools and applications to filter and visualize
// live and recorded data.
