The Mithral Client Server Software Development Kit (part of the Cosm project) allows developers to quickly and easily write large scale client-server applications including "distributed computing" and peer-to-peer types. Examples of what this will allow you to build with this technology are distributed.net, SETI@Home, Napster, Gnutella, etc.
The URARFileLib is a small static library that allows you to read files from RAR archives created with RAR and WinRAR. Listing, decompression, and decryption with full RAR 2.0 compatibility is done directly in your application, so there is no need for a DLL or any other external file. It is based on the free unRAR source code by Eugene Roshal, and designed for easy but powerful usage in demos and intros. It is also useful if you want to port your programs since the it is written in pure ANSI C (some parts are optimized in assembly) and supports multiple operating systems.

Mohawk is the next-generation, evolutionary leap from TkApache. It is a full-blown front-end GUI for the Apache Web server for configuration, tuning, performance monitoring, and more. Completely re- written in C, using GTK+/GNOME rather than Perl/Tk, Mohawk aims to be faster and more robust than TkApache.
The NetStream2000 Linux driver provides a proprietary user-land driver for Sigma Designs EM8400-based MPEG-2 decoders (i.e. NetStream2000) and GPL'd kernel modules which provide DVD access (without kernel recompilation until 2.2.15). It also includes a GPL'd DVD player with access to all DVD functionality such as menu navigation, fast forward, languages, subtitles, and so on. Finally, this kit provides an API and the documentation necessary to write customized DVD players.
