GNOME Storage: "Storage is an exciting project to replace the traditional filesystem with a new document store. Storage is part of a larger design for a new desktop environment, more details on that to come. The current implementation offers natural language access, network transparency, and a number of other features."
I already read about such new kinds of filemanagement some time ago.
I'd wish that KDE and Gnome join forces in that area like they did with the Free Desktop Project!
