SiteFusion allows object-oriented PHP applications to operate as OS-native applications through a XULRunner-based thin client. The client connects to the SiteFusion daemon through an ordinary Web server, and applications run in separate continuous processes. Two-way communication is enabled, without the need for additional Web server configurations. The implementation of the XUL framework in a PHP class structure includes an implementation of the Mozilla tree view optimized for very large trees, supporting drag-and-drop, editable cells, and sorting.
Daemon Manager allows non-root users to start and stop their own daemons. It is appropriate for running FastCGI servers, torrent servers, or any other daemon that isn’t meant to run in the root context. Daemon Manager will monitor processes and restart a daemon if it exits or crashes. Daemon Manager allows the system administrator to decide which users can launch daemons and what users they are allowed to launch daemons as. For instance, it is common to launch FastCGI servers as a different user ("www-data" on Debian or Ubuntu).
pyscmpd is a music player daemon designed for use on Raspberry Pis. It implements a subset of the MPD protocol, but instead of serving local MP3 files, it connects to SoundCloud.com and serves the streams found there. It supports a huge number of front-end clients through MPD, including ncmpcpp and Sonata. It allows you to configure which parts of SoundCloud are made available for browsing by defining categories and adding groups or users to them.
SyncServer is a Firefox sync server written in Perl. Mozilla's Firefox sync server, which is written in Python, has many dependencies and is quite tricky to install on enterprise distributions which don't ship with all those requirements. This syncserver implements the syncserver user API and storage API as an fcgi application. It is entirely written in Perl.
