Isn't it weird how we have these things in our cultures? For instance, tipping in the US is a purely cultural phenomenon (restaurants exist and have great service in other parts of the world where tipping is not common), yet, speaking as one who lives in the US, the pressure to tip is strong. If tipping had no social pressure (and no fear of retribution a la waiters spitting in your food), if it was, like v4v, just a goodwill payment, it would probably be much less common.

If v4v is going to work, it will somehow need to be hooked up to social pressure. Bad as this sounds, there needs to be guilt or public shame associated with failing to zap if zaps are ever going to be a real revenue stream for artists.
