Yeah, I was hoping to get around the re-calculation of the (read) postage stamps by enabling the preview image in the exr, but no dice - they seem to work like you said, they get calculated across the board. It's a waste of cpu - when a big script opens up, it takes a while to recalc the reads (instead of the image!), not to mention again with every frame change. I would have thought it was already a feature in nuke from a long time ago, from when systems were a lot slower. Maybe reading the previews take just as much resources as re-calculating...
