It doesn't save bandwidth on the clients. It saves bandwith on the
servers. There are a lot more debian mirrors than there are debian-cd
mirrors, and they're a lot better distributed as well. The rsync just
blends the downloaded packages into a iso-compatible image. Most of that
process is the iso munging, not null blocks.
