If this project is used, then it would be nice to pick a license that best fits in with this mashup. I am interested in maintaining the freedom of my code but do not want to create a catch-22 or make life hard for people who need to use this project for personal use or profit.
My inclination is to use MIT's, as I have done so before. I asked an IP lawyer about this matter, and she replied (pro bono), "it probably doesn't matter." Of course, that advice was worth every penny.
Moving away from legal issues and looking at this from a social perspective, which license would appeal most and offend least? I thought about no license but was warned (pro bono), "If you do not, then someone else may." That one might have been worth paying for but please do not tell her
