RIAA vs P2P?

• Peer-to-peer is larger than file-swapping.

• P2P = Power to the People?

• Where does copyright fit into the picture?

• Fair use for powerful users.

Clay Shirky

Definition of P2P:

An application is P2P if it aggregates resources at the network’s edge.

P2P applications address the nodes outside the DNS.

Clay Shirky

• “Because you could not get an IP address for your PC, you could not really host anything. The veil of second-class connectivity created a second class of users.”

• Balkanization of the address space (ICQ and AIM have created 150 mln cf. to 22 mln in whois)

Clay Shirky

One-liners:

He overestimated by four.

Thomas Watson said in 1943 that

“I think there is a world market for maybe five computers.”

We now know that that figure was wrong.

PC is the dark matter of the Internet.
