Instant messaging

Instant messaging is the act of instantly communicating between two or more people over a network such as the Internet.

Decentralized instant messaging

Some newer concepts of instant messaging try to make a decentralized instant messaging system via peer-to-peer technology. In such a system, a distributed hash table lookup is used to determine if buddies are online or not. This approach tries to make instant messaging independent of a central authority.
