I think that trying to use a Sampling Plus license (or whatever) as a promotional vehicle is just plain silly. The only people that care are about 80 bloggers and internet radio station operators that live on the outskirts of San Francisco.
(Unfortunately, one of those people is Cory Doctorow, and he just won't shut the fuck up. It makes the rest of us, people that are actually creative instead of just pretending to be so we can get speaking fees, look bad. "Hey, look, my latest terrible novel has been machine-translated in to Farsi backwards, and every third word was replaced with an icon that represents Mickey Mouse. Aren't I charming?")
