I used to use Miro, just to download torrents, about a year ago. My use case was to watch Ted Talks. You can search for RSS feeds from within it and once subscribed, select what items it downloads from within a feed. Once a video is watched, It'd be auto-deleted a week later, unless the user decides to keep it. It was actually pretty good. Eventually I ran out of hard disk space and decided to delete all the videos and uninstall Miro.
