The map object seems to be one of the biggest mysteries it arrived.
Maybe someone could explain excactly what it does, what it "replaces",
and how to use it properly?

Subject: Re: tip about fog, skydome and DOF
Hi Arjo,
I often use a squashed sphere as fog object, with a parallel fog
mapping. And instead of using a constant turbidity, I use a curve with
Mapcoords.Z as input, resulting in a gradient atmosphere: turbidity is
decreasing with height. I'll have a look at it again, will upload a
sample project later... and how to implement the mysterious Map object??
(quote "Map object computes the mapping coordinate projection from the
given parameter." - yeah, that explains it all ;)

Yes I prefer this type of fog too instead of the post
one.
From your answer I understand you use a sphere object
for the fog?
I use the atmosphere object (in the lights tab, the most
right object).
That one doesn't have a size.
PS volumetric fog without volume shadows is
fast, I prefer that to post effect fog because reflections etc are
correct.
