The Flex team is constantly looking for Flex applications that we can use for a variety of purposes. One crucial purpose is our ability to test existing applications against newer tools (like for example a new Player on a new OS) to make sure everything is kosher. If you have an application that we can reach please let us know via the comments. If you’d prefer not to publicize your URL but still want us to test, you can send the information to me at mchotin AT adobe DOT com.
Of course we’d love to see public apps for other purposes too, like demonstrating the building power of the Flex community! Would folks be interested in an application registry similar to what flexcoders.net started for developers?
