Oh, this in fact might make things much easier. D-Bus activation
provides exactly that -- if something tries to call a method on that
service, and it's not running, it will start the service.

Thus if we are *only* concerned about method calls, we can use d-bus
activation as it is. But if we *also* need to react to signals sent by
cups/hal, etc., then we need something running already, since d-bus
activation doesn't trigger on signals.
