Skip,

Great idea to get the dimming effect. I took a quick swing at it and I like
the results...

Here's my sky_sphere:

  sky_sphere {
      pigment {
          function { max(min(y,1),0) }
          color_map { cm_realsky_01 }
      }
      scale (1/2)
      pigment {
          function { abs(max(min(x,1),-1)) }
          color_map {
              [ 0.0 rgbt <0.1, 0.1, 0.1, 1.0> ]
              [ 0.2 rgbt <0.1, 0.1, 0.1, 1.0> ]
              [ 0.6 rgbt <0.1, 0.1, 0.1, 0.9> ]
              [ 1.0 rgbt <0.1, 0.1, 0.1, 0.6> ]
          }
      }  
  }
