Hugin Panorama Photo Stitcher

I'll keep this short and sweet.
Hugin is a great tool for stitching together multiple images into panorama views, as well as removing perspective distortions.
It works great (I'm using it to make accurate photorealistic textures for buildings in Sketchup)
It's Open Source, available on SF, and even comes in a handy-dandy no-install zip format.
In its current form, it writes to the registry.
It's based on an Open Source set of tools called Panotools.

Anyone think it's worth adding?

BTW, I've searched here first, and no hits for Hugin or Panotools.
