Good film explaining Zoho Showtime

This is one of the best films that you have created so far about how to use ShowTime.  However, I still need more clarification about the real difference between REMOTE SESSION and FACE-TO-FACE SESSION (I understand ON DEMAND SESSION) as the example doesn't quite do it for me. Can someone put this into different words to help?
