By alternating and pausing one renderer each mainloop cycle and drawing to a black and a white BG, we can generate an alpha mask easily for a perfect composite of Flash with gradients and glows on top of any v4 layer. Add in a two-way Socket Proxy and we have full communication between the two worlds with mouse translation!
Achieved 60 FPS with Flash and a 60 FPS encoded WMV on a Quad Core.
