On Tuesday voters in Takoma Park, Maryland, got to try out a new, transparent voting system that lets voters go online to verify that their ballots got counted in the final tally. The system also lets anyone independently audit election results to verify the votes went to the correct candidates.

From 2003:

Why not publish all the votes on the Internet? When I vote, I get a random number. I can go on the website later and verify that my random number got tabulated correctly. I can count all the votes on the website using my own software and decide for myself who won the election.

(Not saying I had any influence on this, I didn't. Just saying, this has been a good idea long coming.)
