Nephthys provides a Web interface to create file-sharing "buckets", through which data can be shared. Nephthys handles the buckets in the local filesystem of the server. Access and data transfer is made via FTP and WebDAV. Nephthys itself does not provide the access protocol, but relies on well known projects like Apache HTTPD (WebDAV) and ProFTPD (FTP).
6's Spiffy AudioGalaxy Query Tool is a package that automates queries to the AudioGalaxy music sharing system. It enables you to queue any song (at a minimum configurable bitrate) with one command line, even if the AudioGalaxy site is busy or unresponsive. It will also allow you to queue most full albums with one command line, by going on AllMusic.Com to look up the song list, and queueing up each of the songs listed.
zfec is a fast, portable, and programmable implementation of erasure coding. It includes a C library, a Python library, and a command-line tool. Erasure coding is also known as "forward error correction", which is the generation of redundant blocks of information such that if some blocks are lost then the original data can be recovered from the remaining blocks. The RAID-5 algorithm is an erasure code, but while RAID-5 can recover from the loss of any one element, zfec can be parameterized to choose in advance the number of elements whose loss it can tolerate.

NetMess is a peer-to-peer file sharing system. Its advantages over other p2p systems include clone detection and the ability to work through an HTTP proxy and through most firewalls (both inbound and outbound). NetMess can also run in a LAN environment, serving as a nice information sharing system for small to middle-sized companies. NetMess allows its users to search and retrieve documents without having to remember their exact location.
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.
Coquelicot is a “one-click” file sharing Web application with a focus on protecting users’ privacy. Its basic principle is that users can upload a file to the server, and in return they get a unique URL which can be shared with others in order to download the file. Coquelicot aims to protect, to some extent, users and system administrators from disclosure of the files exchanged from passive and not-so-active attackers.
