Gspoof is a GTK+ program written in the C language which makes it easier and more accurate to build and send TCP packets with or without a data-payload. It's possible to modify TCP/IP fields and also ethernet header working to Link Level. You can send one or more packets together. It runs also in "console mode" without X and so you can compile it without GTK+.
Mnet is a universal file space (a single, global virtual space into which you can put, and from which you can get, files). It comes with a single global namespace so that there is no conflict over filenames. It is also an emergent network, one in which the important features of the network result from the interactions of nodes operated by autonomous people or organizations who do not explicitly coordinate with one another. There are many interesting applications that can be built on top of an emergent network and a universal file space. The first application that has been written for the Mnet project is a file-sharing application which lets you search for and download files of all kinds from the universal file space. Mnet is descendant of Mojo Nation.
jSyncManager is a Java-based data synchronization toolkit for PalmOS handhelds. It consists of a developers API, including a fully Palm-compatible synchronization protocol stack, and a set of end-user applications. It is ideal for use by any individual or organization that needs fast, stable, and easily extendable PalmOS handheld data synchronization that can run on a variety of platforms.

The Hunting of the Snark Project contains a client for downloading and sharing files distributed with the BitTorrent protocol. It is mainly used for exploring the BitTorrent protocol and experimenting with the GNU Compiler for Java (gcj), but it can also be used as a regular BitTorrent client. Snark can also act as a torrent creator, a tiny HTTP server for delivering metainfo.torrent files, and has an integrated tracker for making the sharing of files as easy as possible. When you use the --share option, Snark will automatically create a .torrent file and start a very simple Web server to distribute the metainfo.torrent file and a local tracker that other BitTorrent clients can connect to.
apt-got is a customizable mirror engine. It works like a highly specialized proxy. It employs several pluggable modules that are customized for specific jobs. The first available module builds and supervises a partial (or full) Debian mirror which is populated on-the-fly by apt-get requests. There is also a simple mirror module that can be used to mirror source directories or even (static) Web pages. For increased performance on already-cached files, it employes its own Apache module. It supports customized mirroring algorithms.
Devalot is a social networking application centered around software projects. It connects the user community with the development community and encourages participation and communication. It includes all the features you've come to expect in modern Web-based applications such as tagging, comments, and a wiki, as well as features you'd expect in project tracking software such as ticketing. It has features similar to some of those found in Trac, Collaboa, GForge, Mephisto, and Typo.
