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.
