I have an iMac running Snow Leopard so I will be upgrading my computer via the Mac App Store. My wife, however, has a Macbook running Leopard. Will it be possible to download Lion from my iMac and make an installer DVD or USB stick to upgrade her computer? Does it ask you for your Apple ID when installing this way in order to verify that you're on the same account? Otherwise wouldn't this lead to rampant piracy? I'd really rather avoid having to purchase a Snow Leopard upgrade for her Macbook if I could just directly upgrade to Lion from Leopard with an install disk/stick. Thanks.
