Any beer recipes using cacao nibs?

[Otterbrew]

During a tour of Scharfen-Berger chocolates, I bought a box of these bitter things thinking I would make a chocolate Stout or something along those lines, so I am wondering if anyone has ever used nibs in their beer, and is willing to share the recipe and how the nibs were used.
Thanks,

Sam Adams uses them in their chocolate Bock.
