I dunno. I could see it... As long as you access the "iCloud Web Service" from an iDevice or a Mac there will be loads of useful and functional tools and features for you to take advantage of. It'll be 4x more expensive than AWS but the integration with Apple's ecosystem will be fantastic!

If you try to access it from a PC or an Android device though you'll have your bandwidth throttled and all your images will be reduced and compressed like it's 1999.
