Dean writes "Democracy Player, the open source answer for RSS video aggregation/playback, has just made it to 0.9.2 for Windows, Mac and Linux. If you haven't tried Democracy Player for a while, it's time to try it again. The application is more responsive and stable, uses less memory, integrates Bittorrent, and can now play Flash videos (including stuff from YouTube, Google, Yahoo, etc). Democracy takes all the hassle out of finding and watching videos from your favorite sources."
In many ways, Democracy is the template of what I'd like to see out of Apple's upcoming iTV. Although my guess is that it will be more like MythTV- only for people willing to put in the effort.
