Vote via E-mail - Someone Shoot Me Please!

In an article in the Washington Post, that is currently being discussed on ZDNet (http://government.zdnet.com/?p=2690), the Pentagon reveals that it will be allowing deployed soldiers to vote via E-MAIL! (Orig. WP Article is HERE)

As a Network Security Administrator, I don't know what scares me worse... The fact that the Pentagon came up with this in the first place or that they actually DO NOT SEE WHAT IS WRONG WITH THIS PICTURE! I understand that most average users are under the MISTAKEN impression that their e-mails are sacred and private, but hearing that the Federal Government is going to allow this as a method of choosing our nations elected officials is absolutely mind boggling!
