Forban is a P2P file sharing application for link-local and local area networks. Forban works independently from the Internet and uses only the local area capabilities to announce, discover, search, or share files. Forban relies on HTTP and is opportunistic, meaning that it replicates any files of interest seen in its proximity. The Forban protocols are minimalistic to ease the production of other implementations.
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.
Twibright Twig is a static HTML photo gallery software that supports organization of JPEG and PNG images into a directory structure and EXIF and JPEG comments. It is meant for more experienced users rather than newbies. Three levels of downscaled image and three levels of thumbnails are generated. Each image is assigned a unique identifier to faciliate easy random linking from a master Web site. It handles reasonable large galleries (and is currently used for a 3GB one). Automatic regeneration of added, changed, and deleted images can be done with one script.
