I work in the MP3 player industry, so the title of my review is only a slight exaggeration. P2P technology created the MP3 revolution. This book takes an honest look back at where P2P came from and where it is going from several different viewpoints. I think it is a must-read for anyone working on the future architecture of computing technology. And it is just plain interesting if you are sitting on the sidelines — and you might just find a role you can play in the game.
