Peer-to-Peer

Preface

Andy Oram, O’Reilly & Associates, Inc.

The term peer-to-peer rudely shoved its way to front and center stage of the computing field around the middle of the year 2000. Just as the early 20th-century advocates of psychoanalysis saw sex everywhere, industry analysts and marketing managers are starting to call everything they like in computers and telecommunications “peer-to-peer.” At the same time, technologists report that fear and mistrust still hang around this concept, sometimes making it hard for them to get a fair hearing from venture capitalists and policy makers.

Yes, a new energy is erupting in the computing field, and a new cuisine is brewing. Leaving sexiness aside, this preface tries to show that the term peer-to-peer is a useful way to understand a number of current trends that are exemplified by projects and research in this book. Seemingly small technological innovations in peer-to-peer can radically alter the day-to-day use of computer systems, as well as the way ordinary people interact using computer systems.

But to really understand what makes peer-to-peer tick, where it is viable, and what it can do for you, you have to proceed to the later chapters of the book. Each is written by technology leaders who are working ‘round the clock to create the new technologies that form the subject of this book. By following their thoughts and research, you can learn the state of the field today and where it might go in the future.
