Looks really smooth. But I think it makes the lines also appear thicker 
than they are. You get a similar result when you just 'blur' the texture in 
POV-Ray and then use the normal aa method without oversizing and scaling:

pigment{gradient y
        pigment_map{
        [0 rgb 1]
        [0.41 rgb 1]
        [0.5 rgb 0.3]
        [0.59 rgb 1]
        }
}

However the bluring would have to be done dependend on the distance to 
remove the artifacts in the mid-distance.

Maybe one could add a 'blur texture when far away'-feature to POV.
