Volumetric Lighting - is it do-able?

[MarkJayBee]

Having seen some of Buddhi's wonderful test renders using his new
'volumetric lighting' feature in Mandelbulber. Naturally, I tried to replicate
the effect myself - alas with only limited success due to incredibly
long render times with Mandelbulber on my old box.

So of course, my question is; how practical would it be to implement
a similar volumetric lighting function in M3D? To have the facility to
introduce atmospheric misty light beams would be the icing on the cake,
especially after the recent introduction of 'reflections'!!

As ever, I live in hope....

To answer my own post - YES!!  It is do-able, as evidenced by version 1.8.9! 
Hooray for Jesse!
