I'll have to take a look when I get to a computer. This would be cool if it got adopted. With modern cameras and shooting in raw, I can tell you how much data is lost. I never print in jpegs because of how much its compressed. I always tried to use tiff for prints. I only used jpegs on my photography websites.
That being said, I can't see a switch anytime soon. Jpegs are so engrained and standard it will be tough to dethrone them.
