Will Election Day Ever Be Online?

As we lineup across the U.S. to cast our votes (you are voting, aren't you?) the archaic nature of it all starts to sink in. In an age in which we can order pizza online, or pay taxes, we have to (for the most part) stand in line to wait to cast our ballots through a variety of methods. Why not cut out the middle man? Could we see voting from home anytime soon? There's several issues to consider: there would be no way to know whether the person was casting their vote under pressure, or with a watchful eye in the room. But given the perceived or real fraud/hack possibilities with today's methods, would internet voting really be any worse?
There are a few hundred people who will actually be voting via the internet this year. But this method utilizes "hardened" PCs on military bases, and isn't a practical way for millions to cast their votes. (As an aside, here's an interesting article on how astronauts in orbit will vote this year.)

Maybe this isn't a problem that requires technology. We could simply go to a mail-in ballot as Oregon has done. In theory, the same issues of intimidation are possible, but overall, Oregonians seem happy with the painless, line-free voting method. Technology, as much as we love it here at TDL, isn't always the answer.
