Ask HN: Corporate structure for software development?

I am writing some software which I hope I can sell for a profit. However, I am concerned about the possibility of being sued. Thus I would like to form a corporation of some sort to protect myself. What should I choose in terms of legal complexity and taxation? (LLC, LLP, S, etc) Also, where should I incorporate in? Keep in mind and it is just myself and I do not plan to sell the company (although I may sell the copyright to the software).
