Have you taken a look at the Flash screensharing functionality? I've never actually implemented it and it seems there are some strange requirements (officialy FMS with some module only I believe,) but it would resolve the trust issue for a lot of people. Perhaps you could try and consider adding it as a fallback or fall-forward (if that's a real word ;).
