Dual 27" display brightness control

I have a 27" iMac and a 27" cinema display. I love it.

I don't like automatic brightness control and I adjust the brightness several times each day. I would like to be able to adjust both screens at the same time. The brightness controls on the keyboard only control the iMac's brightness and not the 2nd display. Is there a way to adjust the brightness on both monitors at the same time?

I also would like to know if there is any chance, to change between the displays (while setting the brightness) if they are more than 2.

Or change them altogether simultaneously?

I have a MacPro set up with 3 cinema displays. And actually i can only adjust 2 of them via the keyboard.

Only the original poster can do that, and he/she hasn't been heard from for about 6 years.
