How can you detect whether a flash swf is paused or not?

Flash never gets instantiated, so there's no chance for us to send out a notification.  It's worth noting that Chrome is pausing content that looks like an ad for power savings, and that it affects both Flash and HTML/JavaScript content.  If your primary content is Flash, it shouldn't get paused.  If it's an ad, you're going to have some interesting challenges ahead.  I expect that there will be an arms race of workarounds and mitigations as the browsers continue to focus on power management, and content providers participate in bad practices like ad-stuffing, etc.
