Blergh, is there a reason it's on the system bus? Running on the session
bus makes it much easier to run multiple sessions, and also the security
policy on the session bus allows things like dbus-monitor to snoop
messages, making debugging easier. The system bus should only be used
for situations where you want user stuff to speak with priveleged
per-machine daemons such as hal, network manager or avahi.
