Fog (Haze) and Volume Light

[skysurfer]

Happy new Year, first.

Could be added, at certain point, the volume light?

And more important will be available a Fog option like in (old) 3DMax?
I find this option lot useful for Arch night view and for make the horizon disappearing.

Could you suggest best way to get this effect, maybe without Z-Buffer and Ps?

Thanks
