Yet P2P offers a great many legitimate benefits. Just witness the recent discovery of the largest prime number, a poster child for distributed computing!

P2P is a class of applications that leverages previously unused Internet resources?storage, cycles, content, human presence. Instead of large, expensive servers and pricey storage networks, corporations and other organizations can share data and computing duties among their desktops through P2P.
