If Site A's swf is emnedded on Site B in terms of iframe, that should carry some value as well (Logically).
It does carry some weight in YouTube search - but whether that extends to Google or not isn't clear. How to handle any kind of iframed content, whether same domain or cross-domain, is a challenge.
Traditionally, iframe content was just a separate URL and that's that. However, last year Matt Cutts did make some comments that this might change. Haven't heard anything on the issue since that time, however.
