well, the easiest way of implementing it is an augmented material type 
with possibility of specifying an additional ambient value, means 
addtional to everything, also to an existing av.. If you want to get a 
feeling how this might look in principle then you can play around a bit 
the with 'ghost' material in current radzilla, which has this feature. 
Although here the original reason for offering it is different, I 
thought of  special cases where one wants to set markers in the scene, 
or for some purely artistic stuff.

One might give it a try and offer this opportunity, although personally 
I still think it will be rather confusing (cf. my remarks on the POVRay 
case..)

Messing with the ambient caches's av itself is btw problematic, because 
of the recursive nature of the ambient calc.

well, sorry, the honesty, of course your're right. How could I.... :-)
BTW, evidently Photoshop has no place in my rendering workflow either.
I use Gimp ...
