I am not a professional programmer neither a professional photographer (even if I make occasionally money with this very secondary activity), and I made this code as a hobby.
Theoretically, my main activity is to make research in polymer chemistry, but in practice and for personnal reasons, I'am currently (march 2011) unemployed for more than 2 years (=> I can sometimes spend quite a lot of timetime with hobby!).
So, I share this code with the pano-photographer community with pleasure, but if you use it in a commercial project... feel free to think to me ;-)
