Non-Governmental E-Voting (a free* idea)
The technology exists for registered voters to vote on important issues all the time, via internet referendums. But no government will do it, because such a level of true democracy would be too scary for them.
But there's nothing stopping a non-governmental organization from doing it!
If you got 1 million voters enrolled, the government would have to listen!
