Stone seems to be pretty good to home brewers like that. I think the recipes for the anniversary ales 1 - 9 have been released in Zymurgy. I emailed Stone for the recipe for 10th anniversary ale and they actually gave it to me. (PM me if anyone wants it; saq I private messaged it to you). I also have the recipe for the 11th anniversary from an email that another person sent to Stone.
The only tough recipes to get are their regular releases, i.e. IPA, Old Guardian, etc, though I can understand why those wouldn't be given out.
