Sturmey-Archer does make a 3 speed fixed gear hub (or at least did) but it didn't work well according to a lot of reports from people who have used it.
Sturmey-Archer has made a number of internally geared fixed gear hubs, most recently the S3X. I believe that they're all out-of-production now. I've had an S3X three speed fixed gear hub on a bike for over ten years now, and haven't had any real problems with it. Apparently the early S3X production had some reliability issues, but they seem to have sorted it out by the time my hub was made. I use the bike as a "bad weather rider," but have put a lot of miles on it, including a couple century rides. My biggest gripe is the odd gear ratios: 1.0/0.75/0.65; I would have preferred two closely-spaced high gears and a big drop to the low gear for headwinds and uphills, like the older ASC hub: 1.0/0.9/0.75
