Google Indexes Flash
Google has announced improvements to their Flash indexing!
Unfortunately, Googlebots do not execute all JavaScript they encounter, so, if your SWFs are loaded via JavaScript, you may want to switch to SWFObject 2’s static method in order to ensure visibility.
For now, only static textual content is crawled but, as a Flash Developer, it's exciting to have Flash applications becoming more legit in the eyes of search engines. For a more detailed Q&A, head over to Flash Charlotte.

I've been asked to launch a full flash website in several languages, so obviously i'm curious to see how this site will be indexed and presented by Google in the serps
If you make each language for the site a separate SWF with static text then the site's overall ranking should be increased. Although I doubt a Googlebot can index more information from a Flash site than an HTML site.
