Kissdcompanion is a GUI program to be used with the kissd daemon and the networked mediaplayers from KiSS Technology. It was written for personal use and as a programming exercise in Ruby, but I decided to make it available to the public.
Its main feature is to enable a sort of playlists and to provide means to manage these lists.
If you chose to download the source only, you will most likely have to install other software to make the program run. The binary download is supposedly ready-to-run on all systems, but the binary file is large; about 6 MB.
