Here is a great widget for your blog/wiki. The player can be customised to fit in your blog's sidebar. SplashCast enables anyone to create streaming media 'channels' that combine video, music, photos, narration, text and RSS feeds. These user-generated channels can be played and easily syndicated on any web site, blog, or social network page. When channel owners modify their channel, their content is automatically updated across all the web pages 'tuned' to that channel.
