Hi Igor, I'm not sure that PS has the same size limitations as LR, the way LR works is it produces a composite DNG so I think that the issue is mainly a limit on the RAW/DNG engine (one of my friends is on the LR dev team so I will ask out of interest). Pano prints are amazing :)
I think my images are hidden from the public, I have to share a direct link for them to be visible. I have a pano head but if I'm shooting hand held or just off a conventional head I tend to overlap by 50%. This typically makes it easy for the stitcher and it's easy to set by eye, you just place what was at the edge of the frame in the centre on the subsequent exposure.
