It is possible but not ideal.  A better way is to keep a DBUS connection 
open and use Inhibit method.  The application (eg. video player) gets a 
cookie to use with a later call to UnInhibit.  This cookie allows 
inhibit requests to be reference counted and provides a modicum of 
security.  When the DBUS connection is dropped all inhibitors on that 
connection are removed.
