Generating flat UV's that pan with an object?

I'm having trouble coming up with the UV's that I would like to be using in my project and I was hoping someone could help point me in the correct direction.

What I'm looking for is very similar to the "Detail Texture in Screen Space" UV's in the help files ( http://docs.unity3d.com/Manual/SL-SurfaceShaderExamples.html ), but when the object pans from left to right/up and down, I would also like the UV's to shift with it so that it doesn't look like you're looking through a window. In the example the UV's are fixed with the unity viewport so it looks like the texture is sliding over the object. I'm looking to avoid that.

 

maybe ?

No, unfortunately that doesn't pan with the camera. It remains stationary with the screen.
