Dan, Great picture! A perfect location for this type of projection.
As Tom pointed out earlier today, I have added a number of new projections into PTAssembler, one of which ("recti-perspective") appears to be quite similar to the Panini projection. That said, here's a page with a few examples I generated in recti-perspective projection using your image (about 235x120 degrees). http://www.tawbaware.com/forum_posts/recti_perspective.htm I think that we must have a slightly different projection formulas because our results look a little different, although they seem quite similar in the central regions.
