Great topic - of growing importance all the time. I prefer the approach of

1. Serve the vanilla html by default
2. Test for Flash capability via a script
3. Use the DOM to overwrite the vanilla html if the user agent is Flash enabled

That basic logic is what SWFObject does so effectively. As a general rule, I always prefer to send the spider-friendly code as the default. Fewer accidental problems that way. Also, I don't trust that any search engine will continue to value <noscript> elements the way they do today,
