Lyra is a front-end to the Music Player Daemon (MPD). Based loosely on the Creative Media Source software, it has the aim of supporting large collections of albums and artists. Other interesting features are the implementation of a local cache of the music library using an SQLite database, increased speed, and flexibility. In addition, Lyra supports integration with the Last.fm service, which includes "Scrobbling" and album cover art.
Coherence is a set of DLNA/UPnP devices, like MediaServer and MediaRenderer. In addition, it includes a well-designed framework to extend other applications with DLNA/UPnP functionality. It also has an emerging DBus API, enabling these applications to participate in digital living networks. It supports Playstation 3 (PS3), XBox, and many other devices.
Linux Kiss Server is an alternative for PC-LINK software. It is compatible with the latest Kiss player DP-600. It makes the selected directory accessible for Kiss players. It can run either as a daemon or in the foreground. It can answer Kiss player queries for a PC-LINK server. It can disable UDP binding completely, so that it doesn't respond to Kiss player "looking for PC-LINK server" queries. The default server port can be overridden.
The tcpsound utility plays sounds in response to network traffic, making it possible for a user to literally listen to a network. It forks a pseudo terminal in which to run tcpdump, parses that output, and plays a wide variety of user-configurable sounds. By interpreting the output in a pseudo terminal, users can first SSH to a remote host if desired.
