In principal there is no reason why overlays could not be applied to 
hardware accelerated video with styled css elements on top. It may 
require re-tooling some of the html rendering architectures .. but that 
is eventually the way things have to go anyway.

Flash 10 for example supports GPU Compositing which greatly accelerates  
combining images, filters, and video.  It also uses GPU Blitting 
allowing accelerated rendering (like what used to happen in flash full 
screen mode) rendered right to the browsers.

There is no reason why browsers should not head in that direction as 
soon as possible if they want to support the same type of hardware 
accelerated user experience soon to be available via flash.
