Will this allow clients to use the Nvidia driver to draw OpenGL or EGL 
into their local buffers with full acceleration?

Assuming this is true, will this automatically happen if clients try to 
make EGL buffers, or will they have to have special NVIDIA-detecting and 
-using code?

Personally I feel this is necessary if wayland is going to succeed. 
Nvidia will likely fix their driver, but only *AFTER* wayland is being 
used. Wayland will not be used by large segments of the Linux 
desktop-using industry unless full NVIDIA acceleration works.
