[Noisebridge-discuss] Is there a good way to do incrementally updated torrents?

[Josh Myer]

I would guess that this is a way to decentralize the torrents, making it
42,827 times harder to interfere with the swarms distributing these files.
 (There's only that many .torrents in the 7z I just downloaded)

Now to find out how many of these rtorrent can handle simultaneously...
