Brewed this myself (more or less @nbspindel's recipe) and it's been in the bottle two weeks. I've started drinking it because I couldn't wait any more, and it's really quite good. Plenty of molasses and vanilla on the nose, nice roasty malt and coffee flavor with notable but not overpowering vanilla to finish. Could use a bit more hops bitterness. I primed it with sugar, and the carbonation is fairly low, but I think just right for the style.
@Brewratt, I used 3 whole vanilla beans, not extract. I actually brought a big bag of them back from a trip to Bali. I soaked the whole beans in vodka for 24 hours to sanitize the outside, then split and seeded them, and put the seeds in about 1/2 oz of vodka to make it easier to add them to the beer. I also added the bean husks. Following @MacGruber's suggestion, I left it in primary for 21 days, adding the vanilla on day 11, and then straight to bottles on day 21. It's not overly vanilla flavored, so I would add more if you want a pronounced flavor.
Pretty good stuff for my second batch...
