Mike Chambers of Macromedia says:
Lawrence Lessig spoke at the FlashForward conference last night in San Francisco. In his talk, title The Cost of Copy Right, he stressed to the Flash designers and developers the necessity of a culture of sharing. While the Flash community has actually been a very open community, sharing content and source, the Flash Player does not provide an easy or standard way for Flash content developers to allow viewers to download their source code (Flash files are separate from their source).
So, I have put together a simple ActionScript library for Flash that allows Flash content creators to easily allow anyone to download the source to their content by right clicking on that content. I have also added a context menu item that allows a distribution license to be specified. Finally, in a nod to Mr Lessig, I have released it all under a Creative Commons license.
