Aren't torrents already decentralized? I think we should keep these things seperate and not try bloat the blockchain, but I think its good if the blockchain technology influences things like this, but again, should be kept seperate.
No way. Torrents files, movies or MP3s are too big. And you cannot insert a file in the blockchain.
I think he's on about the actual torrent file download which is tiny, not what you're actually attempting to download.
Torrent tracker directories aren't decentralized yet.
They are referring to putting magnet links so bitcoin essentially becomes a torrent tracker. namecoin or another blockchain would be better suited for this but nothing can stop someone using bitcoin either.
