The problem is that you need to show them how to transfer the video to their computer, how to create a torrent for it, and how to send out the magnet or torrent link/file. I would never be able to get any of my grandparents to follow and remember any of those steps, let alone teach them why they need to leave their computer on for me to access it. The entire process is painful. I can teach them to upload to Facebook or YouTube easily. Torrents, not so much.

That may be true of your grandmother, but what makes you say it's true of grandmothers in general?
