How Would You Design the Voting Technology?

Bob Glickstein asks: "Punch-card ballot machines are now universally reviled, and we techies all know the perils of electronic ones. But I haven't seen anyone talk about a better solution. It's gotta be inexpensive, rugged, reliable, accurate, verifiable, tamper-resistant, simple to use, and secret. Verifying a vote tally should not result in TV news images of rooms full of election officials, squinting at ambiguous marks on a piece of paper. What contraption can possibly meet all these criteria?"
