Leveraging Development Skills in Other Fields?

It Can't Be All Bad asks: "I've been working as a programmer for a few years now, and I really love the work. I'm trying to think ahead of possible ways to leverage my skills into more specific areas where programmers are welcome and can find work. Areas like bio and chemical informatics appear very interesting ,but for the most part they seem to be for chem/bio majors with masters degrees. My biggest problem is that I'm self taught with only about a years worth of college experience. At this point in my life (with a family, kids, and bills), going back to school just isn't an option anymore. I wanted to know if anyone has had any success utilizing their development skills in specific fields that don't require masters degrees, and what areas I could be overlooking. Like most people here, I just want to be a part of exciting projects with some sort of purpose behind them."
