I know we can’t do this with any copyrighted materials. But a lot of books, music, art, knowledge is in the creative commons. Is it possible to create one massive torrent that includes all that can be legally included and then have people only download what they actually want to enjoy?
Not quite what you’re getting at, but the entirety of Wikipedia without images is available as a 20-30GB download: https://en.wikipedia.org/wiki/Wikipedia:Database_download
