The Invisible IRC Project (IIP) was originally created so that people interested in facilitating privacy and free speech could work to these ends in an equally secure and anonymous environment. It has now become a haven for anyone seeking anonymous, encrypted Internet Relay Chat. The project's inspiration arose primarily from a shared interest in the Freenet Project and a desire to provide the real-time communications capabilities that Freenet could not.
