Octoshape is a peer to peer streaming media server and client which uses peer to peer grid technology to minimize the bandwidth for any broadcaster to stream any material.

Octoshape can be used to multicast stream audio (Ogg Vorbis, MP3, WMA) and/or video (MPEG-4, Nullsoft Video, or WMV and other codecs), or any other stream of data, over the internet. Octoshape uses peer to peer grid distributed bandwidth to minimize the load of the broadcaster's bandwidth where each listener/viewer will relay parts of- or the whole stream they download to several other nodes in the grid.

This is the trick behind octoshape, because it makes the grid 100% stable with no interruptions in the sound or video when peers logoff.
