Folks,
I am pulling all my Flash (pure AS3 project, not Flash CS3) content from a Drupal back-end for SEO purposes. This works great, except the HTML rendering built in
There is an Flex HTML component available that's pretty good. It uses the browser to render the contents.
However it's not free. You will have to invest $149.
You can test the capabilities of this component here.
So long as your project is viewed within a web browser, your best bet would be to overlay HTML content in a DIV or iFrame above the Flash content using a JavaScript tool such as JQery's ThickBox
