I'm not sure I understand how this would actually help you at all. I can't think of any reason that you should be loading elements of our site into your flash application. Regardless, it is not something that we support and not something that we will likely add support for in the future. Our focus is on providing open APIs that can be accessed using standard communication interfaces such as XML and SOAP. The cross domain policy that you reference is a proprietary standard created by Adobe, and as far as I know it is only used by Flash.
