I think it's possible without too much effort to adapt Luxrender to make a calculation of the variance in each stage of sampling and so to reach a variance set by the user.
Thus, the pixels that already have a low variance will not be sampled again, and the pixels that have not achieved the desired level of variance will continue to be sampled.
.. If I'm not wrong I've seen, in some versions of luxrender, a button in the top right corner of the GUI which should have centered the sampling on the selected portion of the image...
