Excellent! I was thinking more about this, and it would provide a rather crafty means of allowing the webmaster to benefit from user submissions -- the books they submit/review would get tagged/linked with the webmaster's amazon ID, so if someone else comes along and purchases that book, it profits the webmaster! I'm sure some users (other webmasters and similarly tech-savvy people) would grasp this, but many, if not most, probably would not. And it really beats the heck out of bludgeoning people with annoying banners they tune out anyway.
