Thanks Tobias, I think SkyFill might work for the not natural skies example you posted. There isn't a "blue" sky assumption. What might make it difficult is if there is not enough HSV difference between the nearly constant color of the "sky", and how that changes to non sky. It would also likely fail for non-normal skies that are in the red-range -- which is a hue value of 0, and SkyFill wouldn't be able to make a negative hue map correctly back to a value near 360.
Oh yes, I have thought an interactive tool would be very nice. Probably not GIMP though -- the programming interface to get at image data is complicated and would require major rewrites of SkyFill. (GIMP does it for good reason because of the way GIMP handles layers and data, so it has to manage large amounts of image data "nicely".) Actually, a nice place would be in Hugin itself. A tab that would be enabled after stitching... I could sure imagine a nice GUI to draw masks, vary parameters etc. But I'm certainly not going to ask for that right now.
