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.

So then all the networks that have done $things to BitTorrent to demote it
to second-rate traffic will suddenly have a bunch of very angry Apple fans
whose downloads are mysteriously having issues.

And then - assuming you intend for more things than just Apple to go this
route - all the CDN's would need to be redesigned to support BT too.

It seems like it'd be simpler for Apple to figure out how to validate a
partial download and then resume.  It isn't like that would be cutting 
edge technology.  I think I might even have seen it happen before.
