Yahoo!’s Web Messenger built with Flex 2

"Seeing as Flash Player 9 is at 84% penetration, it’s time for the big guns to start releasing content that targets this awesome new version. Obviously, a bunch of Flex 2 applications are already in the wild, but I imagine that the next several months will bring an explosion of great new additions. Today, Yahoo! announced the beta version of a Yahoo! Messenger client for the web. Even more exciting, its built with Flex 2! Cross-platform goodness for everyone."
