I think that you should need to represent yourself in person when you vote. And then it should be represented by a tangible mark that can be verified by a human being.
In Canada its simple. You put an 'X' in the circle and thats it. No dangling chads or connect the lines or digital displays.
Its hard enough to get people to think about voting. I don't see why we need to complicate it anymore. Sometimes the status quo works just fine.
