Apple doesn't allow for torrent apps in the app store, so integrating torrent in damus wouldn't go through. But nostr isn't damus and I'm sure someone will integrate (something like) torrent in a nostr client/app sooner or later.
There could probably be a "leech" service (free or paid), through which one could translate torrent to a "regular link".
One can imagine a torrent-like video service "back end" where the social interface is nostr and if you want to watch, you pay sats per MB. Also if you seed you get paid. Some free/sponsored streams possible if someone sponsors them.
These ideas are not new for sure. Just waiting for the right implementation.
