Just for "fun" and to see if I can get into the habit of, I created a quick and dirty pretend-to-be-tutorial @ http://maemo.crochik.com/qt-developm...dbus-interface All that you probably will need is on the bottom of the page (links to nokia tutorials) but, if nothing else, it will be helpful to me to have it documented for when I forget... I will have to deploy a new version of the application that supports the dbus signal and, depending on when you get yours ready, that can start yours. Please keep me posted on your progress and let me know if you need any help.
