HOW TO: best way to share your AR with viewers in an environment - (EDIT vs. VIEWER MODE)

Even if a viewer has downloaded the Aero app, when they open the file, it is in EDIT mode and they have to know to go to VIEWER mode. Is there (and I hope so) a way to share the AR experience so that a viewer can just 'see' the experience in front of them? If they have to 'place' it, that is fine also but once it is placed, it should function.
