I guess we can adjust many parallax problem by hand on any image editor like GIMP, PS or lightroom. If you know how to use some selection tools, copy, paste, rotate, clone and healing you can adjust many hard parallax problems that can happend on a moving scene or in a hand held shot panorama. I almost always do some kind of final correction on my panos, as I want to try to make them as perfect as I can. Sometimes it is a very hard job. On this panorama, for example, I have spent about 10 hours of editing to fix all parallax errors:
http://cartola.org/360/en/2011/06/01/bruno-at-village-rio-verdes-pool/ I didn't use a tripod and this was one of my first experience on fixing parallax errors like this. I sweart I tried to record a short movie from the screen here, fixing the parallax common problems, but after a long time and after 5 tries I got angry and gave it up... I did it many times before, but the tool is failing now, I don't know why... I'll try another day...
