>On Election Night, I saw something being used in California whihc was a touchscreen app at a polling place. What was cool was that it was shown that it would not allow one to select more than one candidate.

Even such backwater counties as Gaston County, NC (my old haunt before the move to Redmond) were using these two years ago. I was amazed to find that the "Silicon Valley of the Northwest" is still using dead trees and ink.
