archive.org does use torrents and I have one such torrent laying around in my client, which occasionally connects to peers although the the trackers are currently offline. I suppose a new client would find me and other peers through the DHT. I'd share a magnet link for someone to try, but it's a copyright-ignoring ROM dump archive so it may not be the best idea to post it here.
It's interesting that torrents may not be the first thing that comes to mind. They have the "PR issue" of being the now seemingly mundane way in which we've been downloading DVD rips for the last 20 odd years. Newer technology like IPFS does a better job making the cool core of this technology actually sound cool.
