Plug a ScalarState (ray lenght) into a gradient mixer. Plug the mixer
into the input of the spot in the render tree. Set the maximum value in
the input tab of the mixer, and set the gradient to whatever you like.

You can project an image from the light. Use an Image Lookup node driven
by a TextureSpaceGenerator. It has the disadvantage that the projection
is parallel (instead of conic, like a normal spot) but can sometimes be ok.
