Cellar-Door
Cellar-Door is a scallable cellar management system relying on plugins to handle different kinds of beverage. Unlike most cellar-mangement systems, Cellar-Door does not provide a bare view of your current cellar contents, but rather tracks bottles movments (entries, removals, and so on).
Cellar-Door is FLOSS, is designed with extensibility in mind, is written in C# and should run on most desktop operating systems (GNU/Linux, FreeBSD, and probably many other).
Status, as of March 2011
The project is currently under early development, and is brought to life by 5 students at Université d'Auvergne: Cédric Robert, Guillaume Bastide, Nathan Stiz, Nicolas Chaulet and Thibaut Vescovi.
