It should be fairly easy to change this so the event gets enabled for any new user-space process that registers itself with the session daemon while the session is in existence.  This would be possible only for instrumented applications, of course.  It should also be possible to extend this to uninstrumented applications, as long as the session daemon watches for new processes being launched.
