FWIW: I didn't encounter any crases in any recent ML builds. Since Apple is on a one year release schedule now, the differences between versions will (probably) not be as big as before. Also, I never had any problems downloading Lion or Mountain Lion from the App Store. The downloads were always fast (I am on a 120 MBit downstream connection). One would expect that they also release it on a USB stick as before (or DIY).
