This is awesome - and you've got some great advice.
The following was just inspired by the idea of yours "1fps screen sharing":
If you do 1FPS screen sharing - then create a private gallery on imgur.com - and have a thing update screenshots in a single gallery with a garbage collecting thread deleting a screenshot every 30 seconds/interval...
then have user have hidden gallery url and auto refresh browser tab.
This might work well actually if you have a small data connector and a device that can upload like only when event occurs.
Just upload that to replace the file in the imgur gallery - and you have a free cloud cam.
