D-Bus is just a communications bus.  You need to look at the HAL specs
to see how to listen for hardware changes.  Take a look at
gnome-volume-manager which handles CD's/DVD's in a users session.  Just
note that the HAL and D-Bus in FC3 are significantly different than the
ones going into FC4 because of API overhauls.

If you have any other questions about HAL and D-Bus please post their
respective lists.
