Tim,
Unfortunately, that produces:

 density
            {
               agate
               agate_turb 1.0
               color_map
               {
                  [ 0.0     rgbft <0.0, 0.0, 0.0, 0.0, 0.0> ]
                  [ 1.0     rgbft <1.0, 1.0, 1.0, 0.0, 0.0> ]
               }
            }
         }

and not

 density
            {
              density_map
               {
                  [ 0.0     rgb ... ]
                  [ 1.0     rgb ... ]
               }
            }
         }


Your suggestion produces a color_map which alters the colors of the media
through its depth and not the density of the media through its depth.
