Re: iOS 7 update traffic

That's just the typical Bittorrent /client/, but the idea of using
Bittorrent means the /protocol/. A special Bittorrent client could be
written for ISPs with uploads disabled and Apple could also disable them
on the update-downloading Bittorrent client for the phones.

The clients (be it Bittorrent or not) would still download the MD5 hash
after the download finishes to verify the integrity of the download, and
Apple would still be able to measure the amount of downloaded images.

For the ISP, this would mean minimal amount of effective downloads.
