Fair point. This problem could be alleviated by @InflatableDodo's comment of using other nodes (devices) on the network to cache the video, so even if the sender went offline, another node could make the connection with the recipient when they are both online. Sort of like seeding a torrent, except in this case, the video gets wiped upon confirmed receipt. Of course, this is more viable if this gains a large network.
