Graham Sanders and Ian the Cellarman have recipes on their website. I also know they're in close contact with a gentleman that is a maltster of millet, sorghum, buckwheat, and something else. Shoot those two crazy Aussie's an email and I'm certain they'll be able to help you out. http://oz.craftbrewer.org/
I also listened to an episode of their podcast where they tasted a couple of different gluten-free beers that Celiac's can enjoy.
