Just had this idea pop up in my mind. Instead of relying on volunteers mirroring package repositories all around the world, why not utilise BitTorrent protocol to move at the very least some some load unto the users and thus increase download speeds as well as decrease latency?
There is an apt variant that can do this, but nobody uses it. BitTorrent isn’t great for lots of small files overhead wise.
IPFS is better for this than torrents. The question is always “how much should the client seed before they stop seeding and how longs should they attempt to seed before they give up”. I agree something like this should exist, I have no problem quickly re-donating any bandwidth I use.
