I just came accross KickApps, a pretty slick set of tools that allow site managers to easily integrate CGM content and social networking into their offerings. There's a free ad supported model, or you can brand it yourself and pay on a CPM basis. Similar to Brightcove, though the video quality is not as good and i'll bet Brightcove has more player customization options. However KickApps seems to push the social factor farther, and gives you widgets (like the one above) to spread around. I wish you could play videos right in the widget (like Springwidgets) but KickApps is designed to bring traffic from the widget to a site. Still, a really nice way to integrate CGM and brand content into a single platform. From KickApp's front page:

A KickApps-enabled website provides your visitors with a complete rich media community experience. Users are invited to upload media and create their very own “personal space” directly at your site. Site visitors are provided with easy to use media management tools to manage their personal space. Similarly, your site administrator is provided an array of easy-to-use media management and administrative tools to ensure that only appropriate content makes it on to your website.

Here's the execution that caught my eye: http://www.lemonyourwidmer.com/
