Stream Output.

In the last days i have been reading the current stream output, and finally i have a conclusion i like you confirm me.

The RenderToVertexBuffer object make use just of two shaders Vertex and Geometry, it actual usage is create geometry from nothing ( no base mesh ) and then stream out the created geometry to a vertex buffer in a ManualObject.

Currently to do a god rendering using tessellation multiple render passes are needed and tessellate on each pass is not a good option. The main logic to do it is the shown bellow.

As you see it simply tessellate in the first pass and then stream out to to second pass to just shade with the pixel shader. This job as i saw in the code is not implemented, and i just want to know if i'm wrong. if yes a point to it may be beneficall, if not i am planing to implement it because it is a crucial need in the rendering pipeline.
