I tried a similar thing once. It's possible to make it work quite okay for 
stills, but it has some shortcomings. For example, when looking down, the 
grass is still stretched directly below the camera, where you would see the 
grass blades from above. In the end I also wanted something that worked for 
animations too, which led me to try a different technique to fake grass in a 
texture. I ended up creating a texture that does something similar to faking 
many textured planes on top of each other, and released it as my Grass Tex 
Include File.

There's something I don't understand in your picture though. Grass blades 
are visible both in the foreground and on the more distant hill, but even 
though the distant hill is much further away, the grass blades seem to have 
almost the same size. Is that a side effect of the technique you use?
