Basically make it like dropbox. With an app/program installed on either mac or pc to put folders, pics, videos, files etc in to sync across devices. As far as I'm aware, icloud as it stands its basically for backing up your idevices and syncing some basics features such as contacts, calendars & bookmarks etc. It would be cool if they added features like dropbox and released an "icloud" app for iphone/ipad to view your data.
