Icecast
Icecast is a streaming media project released as free software maintained by the Xiph.org Foundation. It also refers specifically to the server program which is part of the project. Icecast was created in December 1998/January 1999 by Jack Moffitt and Barath Raghavan to provide an open source audio streaming server that anyone could modify, use, and tinker with. Version 2 was started in 2001, a ground-up rewrite aimed at multi-format support (initially targeting Ogg Vorbis) and scalability; this rewrite was released in January 2004.
