jigdo ... I have seen that for debian.
Indeed, but there was a lot more in my post than merely jigdo.
Why not just use bittorrent, do we really need a third way to get isos too?
Because bittorrent downloads everything from the net, while jigdo can put together DVD images from CD images, or vice versa, or CD/DVD images from a normal RPM mirror. Bittorrent would require downloading everything of the net in such a situation, while jigdo would download maybe 50MB for a 4CD set or DVD and get the rest from local sources (HDD/CD/DVD).
And why did I mention it? I keep a local mirror of RPM packages but just lately required both CD and DVD isos for friends, so I ended up downloading _EVERYTHING_ again - seems VERY wasteful. Especially considering it's not much extra work, etc.
