I was under the impression that you couldn't even get viewer data unless the viewer has your app installed. Thus, if you have a viewer object, you know the viewer has the app installed. If attempting to grab the viewer fails, they don't have the app. A viewer.hasApp() function might not help much... if you had a viewer object and were able to call that method, you would already know the answer before
