You may be interested in the technique Amy Hoy recommends in her 30x500 app development course, called a "sales safari." See her blog (unicornfree.com) for details, but the basic idea is to find out where people in a given niche/business hang out, and then lurk there, documenting what you see. Common watering holes are usually places people complain about things and commiserate, and paint points are likely to come up there. This works better than asking people what their pain points are. For heaven's sake, if you want to know what someone really thinks, asking them is often the worst approach to take!
