Basic Elements - 1
File transfer—This is moving a binary from Machine A to Machine B without need for a human to do much more than click a button
File sharing—This is the set of security bits that tell another system that it is okay to read, change, copy, or perform some other function on another machine offering a directory to the public or to users with specific permission

AIT
Basics - 2
Telnet services—The basic plumbing of any Internet Protocol function resides in some form in peer-to-peer architectures
Instant messaging—America Online type communications with provisions for voice and video
Software transfer and distribution—Mechanisms to distribute to multiple clients

Internet Telephony
Initiate a call and transmit it to any telephone in the world.
Mouse button controls when you want to speak or listen to the other party.
Link learners and trainers Cost around 10 cents a minute to dial any
place within or outside the United States. Minimal security www.net2phone.com

Second Generation Systems
Mostly baloney Virtual auditoriums where peers can co-
edit or analyze files in real time. Tomoye (www.tomoye.com)
– Community Web portals– Example: One Fish

Third Generation Systems
Peer-to-peer architectures Minimize bottlenecks Provide “core” features:
– Messaging– Shared file access– History / archive– Support for rich media -- if bandwidth
available
