Correct me if I'm wrong but this seems almost identical to the versions feature in os x lion. Won't this be somewhat obsolete when adobe starts supporting versions on lion?
The short answer is that it is indeed very much like iCloud for Photoshop, though we're rolling out support for more filetypes over time. If we were to stop in our tracks and cease development, it might be something to be concerned with. There's so much in the pipeline that we're not too focused on it at the moment.
