pidgin-osd is an application that uses the xosd library to print various events on the X root window on receiving incoming messages from pidgin. It is based on gaimnosd 0.7 (the last publically available version). It is mostly like the gaimnosd plugin; the only difference is that an implementation for UTF-8 conversion to the current used locale was added.
IM-Filter is a daemon that runs on a firewall and filters ICQ traffic. The daemon can identify file transfers, handle UIN and word blacklists, manage a list with currently logged in users, and log messages sent via the ICQ protocol. The modular design allows implementation of other protocols like MSN or IRC.
sim (simple instant messaging) is an IRC client specialized for use with bitlbee. It is based on sic (http://suckless.org). It reads commands from standard input and prints all server output to standard output. It also multiplexes all channel traffic into one output, so you don't have to switch to different channel buffers. sim must be customized by editing its source code to insert the correct username, server, password, and identification information.
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.
ImageIM is a plugin for Gaim that lets buddies send screenshots to each other via HTTP. Users can simply click the ImageIM button, select a portion of the screen, and then send their buddy the image. If the buddy doesn't have ImageIM, they will receive a link pointing them to the image.
OpenGaim is an instant messaging or "text chat" client capable of communicating over many protocols, including Jabber, AOL Instant Messenger (AIM), ICQ, MSN Messenger, Yahoo! Messenger, Internet Relay Chat (IRC), and more. It is a loose relative of the Gaim project and contains much of the source code in Gaim itself. However, OpenGaim aims to provide quicker releases to fix major problems, and advanced customization options and features not available in Gaim.
