This is the panorama hfov, which should hopefully be bigger as the input 
images hfov. What is the hfov of your input images, and how many do you 
have?

Hmm, I'm not sure if this is going to happen soon. sounds like a lot of 
work without a really big advantage, as one can already launch 
autopano-sift from within hugin.
