Sounds exciting Greg. One caveat I'm sure you probably already know about, but is worth repeating is Amazon's contract item that states you can't put work out in other venues for less than what you price it for on Amazon. Not a problem unless you are wanting to use the same item for promotional use (ie. give-aways). Anyway, as I said, sure you're aware but just thought I'd mention it especially in conjunction with an iphone app. Cheers.
