It would be nice if you borrowed the technique used by Shazzam to eliminate the need for installing/updating the DirectX Runtime. While the existing technique is a huge improvement over installing the DirectX SDK, Shazzam's technique of just embedding the D3DCompiler is even better from an installation point of view. Removing the need to update the DirectX runtime everytime you want to install/update the ShaderEffect Generator would be make the process much faster.
