The Open Source Initiative: History of the OSI I'm working on an article about business applications of Open Source software and this is a good description of how the OSI movement evolved out of the earlier free software, Debian, and GNU movements. I'm struck by the fact that an O'Reilly conference helped crystalize the movement soon after it adopted the Open Source moniker. O'Reilly recently organized one of the first, if not the first, peer-to-peer (P2P) conference in February, 2001. I wonder if P2P will follow the same path to development. Certainly there are a lot of the same players involved. (www.openp2p.com).
