John Sokol writes "I just heard from a good friend and Linux kernel hacker in Brazil that they have just finished their municipal election with 128 million people using Linux to vote. They voted nationwide for something like 5,000 city mayors. Voting is mandatory in Brazil. The embedded computer they are using once ran VirtuOS (a variant of MS-DOS); it now has its own locally developed, Linux-based distro. These are much nicer, smaller, and cheaper than the systems being deployed here in the US. Here is a Java-required site with a simulated Brazilian voting system. It's very cool; they even show you a picture of the candidate you voted for."
