My solution to this would be two paper cut-outs placed in front of the camera, aligned so it looks like the person in the picture is at the optimal distance, so that it sees only one person at all times.
I think using e-mail as the base of a voting system would be foolproof. The front-end would only accept properly formatted e-mails and process the text in the e-mail, making it impossible to hack the system...unless the system that verifies the e-mail votes is connected to the internet. There are ways to make it so it cannot send any data, it would be much harder to hack a system that doesn't send data because the hacker wouldn't know what did what.
By properly formatted e-mails, I mean the voting office would provide a template for the voters to put the data in.
Re: No, you're overlooking rather severe cultural effects.
" In particular, "country" music is almost unknown. My guess as to why is that those types don't understand computers."
Lol, that's a good assessment. (I prefer no-voice music myself, classical and videogame)
Just think, if the copyright owners sold access to a torrent they owned, they would have next-to-free data transfer in costs. Of course it would be 99.999% profits, so no more $20 DVDs or $49 games, new.
All you have to do for an example of a no-copyright environment is look at the current designer clothes market. So many dresses that are copied, and the originals still sell well. The cheap knock-offs are bought by people what don't want to spend $1000 for one dress. Everyone is happy.
Sadly, I saw something about talks to bring copyright into the designer clothes market recently.
