Same question here.I'd be happy to pay for 20GB, and let my iMac be my "master" copy (with everything) while the iCloud is used as a transfer and syncing mechanism. Or use iCloud as a syncing mechanism to my "master", while storing an optimised smaller version (especially for videos!). But I don't think that's their intention. And it would probably require a method to set which libraries I want synced - not as "clean".
