What happens when the shader is NULL?
Yours will crash - MSDN says otherwise.
Does this work on Pixel and Vertex shaders ?
Does it always return back the first dword as is - what happens if an
invalid shader version is passed in.

I would suggest an automated test across [ vs: 1.0, 1.1, 2.0, 2.1, 3.0 ]
, [ ps: 1.0, 1.1, 1.2, 1.3, 1.4, 2.0, 2.1, 3.0 ] , NULL, and an invalid
You can see some binary shaders in the d3d9 tests.
