I think using hardware mode in the Flash Player is:

1. not safe, memory-wise
2. very limiting in the sense that you can only have one swf instance  
running in the browser with GPU mode on.
3. slower for most rendering tasks the Flash Player performs

Hardware acceleration is good for bitmap stuff and the Flash Player  
is a vector engine at heart. The two do not mix well and require  
separate rendering contexts to handle the two types of content -  
vector and bitmap.

The near-term speedups in PV3D will largely come from the pixel  
bender api, I gather. Both shader api stuff to using pixel bender as  
a generic number cruncher are areas of research - normal mapping,  
textures, volume effects, and even raytracing.
