I’m a big fan of Telemusicvision too. For big brother, have you checked out http://channelchooser.com/ ? Not sure if that qualifies, but there are some big brother cams in there.
Also, I thought you may find “this interview”:http://www.technologyevangelist.com/2006/10/innovators-nicholas-reville.html with one of the Democracy Player co-founders interesting.
