We should Do The Right Thing By Default. Thus, there needs to be a standalone
torrent that has just the DVD ISO (and maybe the netinst ISO) for all those
newcomers who don't know any better, so we don't scare them off with a 9 GB torrent.
In theory, we could have a "menu" torrent to let you download the x86_64 DVD,
the PPC CDs, and the i686 Live image all in the same place, but this would give
us a sparse and somewhat disjoint set of peers in a torrent that's much smaller
than the main single-purpose torrents, defeating the purpose of using bittorrent.
Another problem is prioritization. Right now, if I'm downloading three DVD ISOs
and two liveCD images (not entirely unlikely) I can tell my torrent client that
I really want the i686 liveCD first, and I will get it inside the hour, and I
can play around for a bit while I'm waiting for the rest to complete. If
they're all in a single torrent, I'm stuck sitting on my thumbs for a day while
it randomly pulls chunks that are mostly from other ISOs.
Since bittorrent doesn't have a concept of dependencies (no "metatorrents")
there's no benefit to having multiple files in a torrent unless all of them are
useless without the others.
