Regarding: "It is simply not traditional in politics. It is ubiquitous in business" referring to proxy voting.
I don't think you want to go there. The way "proxy voting" works in business is you give the board your proxy or don't get a vote at all. And if you give your vote to the board, they don't vote your wishes (if they wanted your wishes voted they'd have let you vote...) ---- Election-Methods mailing list - see http://electorama.com/em for list info
