Virtual Multicasting (VMC) is a specific instance of a more general idea, Information Mass Transit (IMT). IMT aims to reduce the waste of bandwidth resulting from individual streams of data, while improving user-level latency. By analogy with mass transit where shared transport reduces the load on infrastructure, IMT aims to use networks and other infrastructure more efficiently. VMC combines some of the benefits of caching (transparency, dynamic adaptation to workload) and multicast (reducing duplicated traffic).
