Update: P Diddy adopted live video with Ustream.tv as a way to drive his audience, according to Mashable and Watching TV Online.
Also, Ustream has "signed Oracle, Duke, Sun, UC Berkeley and Sling as customers for its paid white-label live video service, called Watershed, which launched only a month ago," according to NewTeeVee. Liz Gannes continues, "The company is also adding mobile broadcasting capabilities, which it released to consumer users a few weeks ago. While many broadcasters might be interested in white-label mobile broadcasting, at this point the Ustream/Watershed service is limited to high-end Nokia handsets. Competitors in the consumer space like Qik have moved onto other platforms, such as BlackBerry and Windows Mobile."
Update: Promotional notes in comments are fine, but they should address specifics in the particular post and link to web pages of specific concern.
