Is there an opengl extension that would allow the spot light to work per pixel rather than per vertex?

Using a spot light (even if it worked as you'd hope) would almost be a little too perfect. We'd also need to draw the light beam near the aircraft in foggy conditions. Would love to see a 747 dropping out of the soup from the tower view with it's lights blazing through the fog. That probably wouldn't be too hard to do, and could even be done as an animation as part of the model.
