SWF searchability- SEO for flash and flex.

Adobe is teaming up with search industry leaders to dramatically improve search results of dynamic web content and rich Internet applications (RIAs). Adobe is providing optimized Adobe Flash Player technology to Google and Yahoo! to enhance search engine indexing of the Flash file format (SWF) and uncover information that is currently undiscoverable by search engines. This will provide more relevant automatic search rankings of the millions of RIAs and other dynamic content that run in Adobe Flash Player. Moving forward, RIA developers and rich web content producers won’t need to amend existing and future content to make it searchable—they can now be confident that it can be found by users around the globe.
