Is there such thing as "versioned" torrents? Assuming you have the right PGP key you could mix bittorrent and packaging systems to get an update-able distribution

but unfortunately most foss torrent clients do not support it, partly because at release libtorrent 2.0.x had poor io performance in some cases so torrent clients reverted to the 1.2.x branch
But torrent is probably the wrong tech. I’m sure there would be many players willing to host a few TB or more each, which could be fronted via something so it’s transparent to the user.
But a better option might be a subscription model, anything else will be slammed by crawlers.
