I think those are very good questions. Technically, they seem to use pretty ordinary gear. The bit rate is super low, about 5 bps so you're not going to be sending over your movies any time soon. It's been tried but nobody ever succeeded and conditions would have be just so for this to work.
Possible applications from a practical point of view not that I can see, though I'm sure that now that it has been shown to be possible there will be attempts to replicate it and from harder locations.
But HAMs are known for doing things the hard way, after all, you could just pick up the phone and talk, that's not what this is about. It's about being able to do it, just like mountain climbing.
