The Off-the-Record (OTR) Messaging proxy is a multi- platform proxy that allows you to have private conversations using the AIM client of your choice. It provides encryption, which prevents someone who intercepts your instant messages from reading them, authentication, which ensures that the correspondent is who you think it is, and perfect forward secrecy, which ensures that no previous conversation is compromised if you lose control of your private keys.
licqweb is a Web frontend for licq. It interfaces with the Remote Management Service plugin and uses AJAX to provide real-time communication. It is useful for people who use IMs from multiple locations and want a 'centralised' application that means no more logging off and on, consolidates chat history to the one location, and prevents problems where messages are missed because another IM client received them.
