I haven't came across an app that allows for streaming files from iCloud. For instance, if you have a music file in iCloud on Goodreader, you have to download the file to the device before it plays in the app. I know iCloud Drive is still in Beta, but i'm wondering if it's possible to stream anything from it? The ability to stream music and video from Dropbox has been really nice. I would love to switch over to iCloud drive given the pricing scheme!
