AIMSpy is an application that parses and displays content from instant messaging systems using the local network. It is multi-threaded, uses BPF devices for network access, and includes fairly thorough support for the AIM chat protocol and rudimentary support for the Rendezvous (iChat) protocol.
Atheme IRC Services is a portable, secure set of IRC services that are designed to run on many IRCds. Unlike alternative packages, its core is minimalistic, providing only required functionality. Extra modules that provide functionality you want as a network administrator can be acquired through a module repository. It provides a fairly complete services set, excluding features designed for oper abuse. It also adds a twist on many of the classic features of Services, such as NOOP.
CVSToys is a collection of companion tools for the Concurrent Versions System, better known as CVS. It currently contains FreshCVS, which performs actions in response to a commit. Actions include notification by various methods, updating a working copy, and rsync'ing to backup. Another key feature of FreshCVS notifications is that you receive one per commit, not one for each directory of the commit as loginfo-triggered scripts are prone to do. FreshCVS is extensible with Python, and notifications may be published by a Perspective Broker network service, allowing 3rd party clients to listen in.
Damascus is a GTK+ 2.x client for the Gale communication protocol. It is somewhat modelled after IM/ICQ-style interfaces. If you don't know what Gale is, this client probably won't be very useful; you need a valid Gale key to send anything, and Damascus can't generate them (yet). Gale is also scary and confusing.
Howie is an artificial intelligence agent with a natural language interface (a "chatterbot"). It is designed to be simple to install, configure, and extend. The emphasis is less on simulating a human conversation, and more on providing a "virtual assistant" which provides useful services to visitors through a natural, conversational interface.
IMDispatch is a Perl script that closely emulates the paradigm of telephone support over the AOL Instant Messenger service. Using the Net::OSCAR module to connect to the popular service, the program signs on as a specified user, queues queries sent to the screen name, and uses forwarding to facilitate a conversation with one of any number of available, designated representatives. An administrator can instantly send commands to the program, over the AIM service, to add and delete screen names from the list of representatives and monitor the number available or engaged in a support conversation. End users no longer have to be tied to their phones, listening closely for their opportunity to ask a question, and small organizations no longer have to pay for an expensive multi-line, toll-free number.
