How is this different from the flash crowds caused by hockey championships, or football games, or any of the other 
things that generate a lot of simultaneous interest every once in a while?

Given that the code is signed, I'm surprised that iDevices that have already upgraded the hard way don't advertise a 
"update available" service on local networks. Individual devices don't care where the updates come from, so long as the 
signatures are good.

You'd think that'd have the potential to improve the user experience as well as avoid jamming the tubes, especially in 
highly multi-user environments like university campuses; it could probably halve the network load in a significant 
number of home networks, too.
