Well this is certainly news to me. But seriously the lowest level secure network in the U.S. can tunnel over regular internet with no loss of security and we still don’t have Internet elections?

From: http://en.wikipedia.org/wiki/Estonian_parliamentary_election,_2007

In 2007 Estonia held its and the world’s first national Internet election. Voting was available from February 26 to 28.[2] A total of 30,275 citizens (3.4%) used Internet voting.[3]

Electronic voting in Estonia began in October 2005 local elections when Estonia became the first country to have legally binding general elections using the Internet as a means of casting the vote and was declared a success by the Estonian election officials.
