Exactly.

Me asking similar question - https://twitter.com/stefek99/status/392755432105603072 - I want to find .iso, make bootable USB and wipe everything, start fresh.

Nowhere close to official, but you can torrent it: http://thepiratebay.sx/torrent/9085330/OS_X_Mavericks_10.9_O...

I have always wondered why Apple and Microsoft don't embrace Bittorrent as a perfectly reasonable distribution method for "big bang" releases (like today). I have tried using Burnbit but it is only as valuable as there are folks who use it (Metcalfe's Law strikes again!).

I would also want to see some shas of the files distributed from Apple before I would use something from TPB.

I believe that when you buy things from the Microsoft Store, one fulfilment option is an Akamai "peer download", which uses BitTorrent internally. This was something I used a few years ago, so I'm not sure if it's changed since then.

Not only would it be a better experience for the customers, it would save them a ton of bandwidth as well. I have no idea why App Store doesn't use BT by default and fall back to direct downloading.

YOu can pause and resume download through appstore.
