I thought one of the main reasons for dbus to exist is so rootspace can
broadcast messages to GUI sessions, rather than having to go the other
way. The update agent is run by a cron job, emits a dbus message, and
terminates.

Or, it just writes to a status file. The applet uses the magic of
inotify to be notified of changes. Files are good. Everything is a file.
This way also makes the status persist on the filesystem rather than in
RAM via a heavyweight daemon.
