P2P Researchers Just Support Piracy?
P2P = Illegal File Sharing?

Internet Communication: 1960s and Now
Started as a peer-to-peer system… The early Internet (late 1960s, ARPANET) Goal: share computing resources
The switch to master/slave or client/server The explosion of Internet on 1994 brought millions of people on network People needs just to send e-mail, surf the Web, buy the things
they just request the service and wait for the answer People are just temporary connected to Internet (via dial-up, DSL) Shortage of IP addresses (user-to-host name ratio ≈ 5)
First ARPANET imp log:The first message ever to be sent over the ARPANET from the UCLA SDS Sigma 7 Host computer to the SRI SDS 940 Host computer.
