     Sorry. Obviously not everyone is as experienced and  
knowledgeable as you are.
     I didn't say that it was the best solution; I just said it was  
discussed and while I may not have mentioned it previously, my  
professor highly discouraged the use of polling but said it was a  
viable way to solve _some_ problems. And of course, there are always  
more ways than established in all cases to solve a problem; one must  
think outside the box of course. And that is a design problem worthy  
of any engineer.
