Oops, yes - I've been struggling with that name the whole day ;-)

Hm, I didn't think of that. Actually I'd expect it to improve print quality.
I also guess it depends on the dithering algorithm; maybe that's where a 
benefit of random dithering can be found? Printers should be quite 
immune to random noise in images to be printed I guess.

JPEG and OpenEXR output will not support dithering (nor will Radiance 
HDR for the time being - though it could be of use there - as it is not 
as straightforward as with classic low dynamic range images).
