IMHO that's a backwards way of approaching security.  You will never be
able to define everything somebody should _not_ be able to do.  You
should always take the approach of defining what somebody _should_ be
able to do.

During the recent discussion, somebody mentioned there are also ways to
trigger events through dbus (I haven't looked down that path myself so
I'm not sure of the details).

I don't speak for anybody but myself - that's enough trouble.
