Stream-2-Stream implements multicast+, a next generation streaming protocol (click for more info). Multicast+ is more efficient and requires less bandwidth than direct streaming (e.g. shoutcast/icecast). Stream-2-Stream (abbreviated "s2s" or "S2S") stations have no user limit; stations can be set up without paying a fortune for bandwidth. Stream-2-Stream saves bandwidth by passing streams from one peer to another through multicast and unicast p2p, rather than everyone getting a stream from one central server (Shoutcast/Icecast).

Stream-2-Stream's features include:

• Integrated MP3, Ogg media player. No external media player needed to listen!!!


• Easy to use GUI


• Bandwidth is tested automatically for the best p2p streaming performance


• Settings are saved to xml


• Easy to use server command-line


• A shoutcast/icecast internet radio/TV Station is used as the source


• Freeloaders/Leechers (peers that only listen but don't want to send out the stream to other listeners) will be detected


• The data stream can be signed; you can be sure that it arrives unchanged


• Very efficient communication (low overhead).


• The network structure can be viewed with a monitor


• Peers can be denied service


• Streams can be recorded to files for later viewing


• Integrated Station viewer allows you to listen (or watch) by double-clicking on a station
