But it does, see my other mail!

Unfortunately, there is none. Approvers and Handlers are invoked by the
Channel Dispatcher using D-Bus method calls which naturally specify a
single destination, and the Chosen One can then be assured that nobody
else got the channel. However, as we're talking about D-Bus signals
here, anybody can see them. The CM sends exactly one signal, which can
be caught by any number of listeners for that signal.

Hence, the UI side needs to define clear roles for components, and that
just one component should be handling these kinds of signals by
pestering the user. And yeah, some kind of mechanism is needed to
deactivate our handling if Empathy's is active, and vice versa.
