The App Inventor Beta did not make the cut. Although it was a good idea for creators, Google is dropping this project. You will have up until December 31, 2011 to download all your projects. After that, everything will be deleted from Google's server.
By the end of the year Google will make publicly available the complete App inventor source code. For now, no other open source instance is available to take up the relay for your App Inventor projects. Instead, Google will be funding the center for Mobile Learning at the MIT Media Lab.
Hopefully there will be someone who's going to follow up on that idea.
