I see banners do it on sites all the time -- meaning the animation doesn't start until you scroll down and actually see the swf banner on the screen. If it is off screen it will sit paused until you scroll down. That make sense? Any tricks you know to do that or do you think it's done in javascript page code instead?

In combination with keypress detection it would make a good copy protection. For example, if you display images or text and you dont want them to be copied, you can stop the use of printscreen key detecting its keypress and replacing the frame with a blank one. If the user then goes outta focus to use it, you detect focus is lost and replace current frame with blank one anyways... one could detect ctr+p too in order to avoid print commands when in focus... I will have to test and see how it works out and if I can circumvent it somehow... maybe those plugins that download flash content would break this measure... but it remains to be tested yet... ;) This is awesome.

As for the screen thing, research bitmap data, the screen is actually a snapshot of the movieclip that holds all the objects in. this snapshot is taken everyframe and so overwrites the current one making it look like a video.
