Do you want to create LIVE TV stations online? Check out Mogulus, it’s your online studio where you can create, program and broadcast your 24/7 television station.
Mogulus is out of stealth-mode but still in closed-beta, you would need to apply for beta-account. But it’s worth watching their introductory video tour, very creative.
BTW! Mogulus user-interface looks great and entire application (front-end) is made in Adobe Flex 2.0.
This year is going to be interesting, lots of video-content, tools to create content and hardware (Apple TV) to serve it to TV.
