Hmm, lots of this is what I wanted to do with CDIS :s

Anyway: whilst talking about that several weeks ago with several people,
consensus was it's not a good idea to do dbus monitoring and client
removal in a screensaver, and use "pings" instead. This reduces
complexity and bookmarking in the screensaver.

Next to that, care should be taken when using dbus in security-sensitive
applications, like a screensaver -> the always returning "abort when bus
crashes" issue. You cant allow a screensaver to abort at any time,
certainly not because of some external service.
