Yes, I'm well aware the issue.  Unfortunately there is no immediately
solution in order for the Flash to expose accessibility information.  JAWS
12 changes the wmode dynamically when JAWS is running and it sets it to
"window" but as you know that can have a dramatic effect.

One solution that I recommend is to either detect the presence of the
screen reader or offer an accessibility option which renders the same page
with wmode set different.  This would mean that in accessiblity mode
content would need to be position different so it didn't appear cut-off
behind the Flash movie but allows for different users to access the same
content.  For example, a drop down menu that normally would appear over
the Flash content would appear horizontally above it and push the Flash
content down.

its size (keeping the same aspect ratio) in relation to the user's

Yes, sounds very nice.  I've played around with this technique for Flash
content in general (non-video) by watching the size of the other content
change and using the external interface to resize the Flash content. Flash
is nice in that regards compared to Flex that it allows for this type of
resizing quickly and also allows for zooming based on the IE zoom
