It is part of a larger design for a new desktop environment, more details on that to come in the future by GNOME’s Seth Nickell. The current implementation, built under Gnome for now, offers natural language access, network transparency, and a number of other features. Some additional info is here. Update: Seth is replying at Slashdot about Storage.
