Corona A6 is great...

but I would like to know how:

having in a scene different cameras with their own exposure values, white balance, contrast, clamping.
how adjust the displacement value +/- per object
how to blend a Corona light material with a Corona standard material using a mask

and...

when the RT will be enabled?
when the dispersion will be available? I don't want to use Keyshot anymore.

regards

1, By enabling use photographic exposure in render settings and putting CoronaCamera modifier onto your cameras.
2, Not possible yet
3, Why in the world would you want to do such thing?
4, Probably not in a near future.

thanks
unfortunately is not possible to set the contrast, color balance and clamp for each camera.

for blending Corona lightmaterial and glossy-diffuse mat I can use the self illumination feature, I donno if it's limited.

Regarding dispersion I understand that is not a simple thing to implement.

I noticed that using BDPT absorption doesn't work.

Yes, self illumination is there exactly for those reasons. And BDPT indeed does not support volumes yet. And while cameras do not support white balance and contrast per camera, they do support different exposure, DoF and shutter per camera. Contrast is there either for people who do not do post, or just as a preview tool.

Just throw camera correction modifier on top of your camera. It does exactly the same.

Or use Vray's camera with Corona's mod on top :- ) I like to use Vray camera because I love shift tool.

Shifting is very helpful, but I have to be careful everytime I use it not to overdo it :- ) Can start to look odd faster then vertical correcting if done too much.
I could use a shift lens too... not sure if there's even is any good one for Nikon though.
