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.
STPsim is an application that simulates and visualizes switches using the Spanning Tree Protocol. It features a GUI to build and control a custom network topology. A VPython frontend visualizes virtual switches and network cables in a 3D environment. To visualize STP-states, switches and ports change colors and captions in real time.
MediaTomb is a UPnP media server with a nice Web user interface. It allows you to stream your digital media through your home network and play it on a variety of UPnP compatible devices. MediaTomb implements the UPnP MediaServer 1.0 specification. The current implementation focuses on parts that are required by the specification. MediaTomb should work with any UPnP compliant MediaRenderer.
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.
djmount is a UPnP AV client. It mounts the media content of compatible UPnP AV devices as a Linux filesystem (using FUSE). The audio and video content on the network is automatically discovered, and can be browsed as a standard directory tree. djmount should work with any UPnP AV compliant devices or software servers. Currently tested devices include TwonkyVision UPnP Music Server on Linux, GMediaServer on Linux, GeeXboX uShare on Linux, Ahead Nero MediaHome Server, and Microsoft Windows Media Connect.
