It also connects the applications to hardware (through the kernel and hotplug) so that applications, or other systems which use D-BUS (such as HAL) can be notified when a CD is inserted, for instance. KDE 3.4 adds a media ioslave that handles removable discs and drives, and though it doesn't strictly require a full D-BUS/HAL setup to function, it does work best with it. D-BUS also has the advantage of being supported outside of KDE, making for improved interaction between KDE and non-KDE applications. For KDE 4.0, I believe a more complete adoption of D-BUS in place of, or in addition to, DCOP is planned. But don't quote me on that - the exact nature of the transition was still up in the air, last I heard. Cheers, Christopher Martin
