This is my latest macro. I used a sequential list of normals instead of 
averaging them. It looks okay.

// this method is faster, but requires a focal blur and/or extra 
antialiasing
#declare BlurAmount = 0.1;
#macro BlurredReflectionRegularNormals(InPigment, InFinish, InNormal)
//	texture
//	{
		pigment { InPigment }
		finish { InFinish }
		normal { InNormal }
		normal {bumps BlurAmount scale 0.001}
//	}
#end
