Try playing with the brilliance value in finish, decreasing 
ambient(which probably acts something like emission media), and giving 
some transparence to the color(like decreasing extinction in media). The 
brilliance will vary the amount of "scattering" dependant on angle. At 
least, I think it should, it has in my other tests of this sort.

I never thought of trying motion_blur though(well, I tried it with 
isosurfaces, and even used it to control the threshold, but never 
thought of doing clouds or smoke)...these might behave differently under 
those circumstances.
