For anyone not wanting to mess with SVN on google code, I've added a download of the demo in the downloads page that includes the demo with the full framework source code. This will give you the necessary files to compile the sample right out of the box, or at least get you the full framework source code in one download without SVN.
FYI, the demo was created with Flash CS4. However, all source code is in external .as files, so you could easily recreate the FLA files in CS3 if you have that using the AS files as document classes for their respective FLAs. You can see a live demo here.
Keep in mind its still early, and changes may yet be made to the framework resulting in changes in functionality and/or API.
