    I've never experienced that "wget -c" failed to get a complete
    intact image. Could you please explain in what way torrent could
    complete a download that wget could not?

    How is this different from wget? (Aside from possibly having to do some
    manual intervention?) You seem to be saying that if a server fails, wget
    cannot be used to get the rest from another.

    Well, my downloads are already pushing 70% or so occupancy of my ADSL,
    so I don't think that having more than one source is going to make
    it much if any faster, since it's approaching saturation anyway.
