I can second that - we do a lot of work for European aerospace
companies and it is pretty much all (certainly all the b&w stuff) in
either pdf + G4 or tiff + G4. At the end of the day, you can always
store the entire G4 decompression scheme in a tag (OK, I know I am not
worthy but wth!) and it will cost you a couple (OK maybe a few K) of
hundred bytes per image. And that is if you are REALLY paranoid!
