you can override the opacity using the Matte Opacity, which is a rollout in the attributes editor in standard shaders like Lambert etc.
You could make a ramp texture, remove all the colors except one (make it a shade of gray), and them pipe that into the Matte Opacity texture channel of all your shaders. I suppose you could pipe it into the transparency channel too.
I’m a maya newbe, so I am just thinking out loud here, not sure if there are problems with this technique. I would be interesting to hear if there is an object based opacity controller, like there is in max.
