I've been playing around with the idea of a P2P RSS feed. When I say P2P, I mean true P2P, just you and me, not anyone else or a 3rd party player. As a first step, I just figured out how to hack an Apple OSX Tiger widget and made this one for a rocketboom radio stream:
When you click on the widget, it will stream the audio of the latest
Rocketboom episode. Just playing around (I hacked the rabbitradio widget). The next step is video though so far I have only been able to get the video to launch outside of the dashboard.
