Sounds very interesting. I'll take a look at it when I have time. Seems 
like they also provide the software, even the sourcecode.

Btw. I was thinking about the morph to fit feature that you seem to be 
using quite often. Especially for problems like stitching cracks in the 
pavement etc, where parallax error often occurs, should a image based 
morphing be a good alternative? This morphing would then be done based 
on the multilayer output of panotools. I still have to think about the 
details a bit more, like how the poles of a spherical projection should 
be handled and how it works for areas where more than 2 images overlap etc.
