How about something like R2VB?
I think we can implement R2VB if we want it(it is an ATI hack) by just setting a VBO as a render target. The extensions imply that this is supposed to work, although the performance isn't guaranted to be optimal. I think the biggest issue with R2VB is Alexandre :-/
Well, you can't set a VBO as rendertarget directly, but you can copy the FBO data into a PBO, which you can bind as a VBO. That's pretty legitimate in OpenGL. But I was wondering how hard it would be to use something like that for ProcessVertices.
