I think compression would definitely help. While you are right about the download/gunzip times, compression doesn't help that much. As has been mentioned in -hackers, the ISO images only compress by 3% or so, or around ~20MB. So, instead of a 640MB ISO image, you have a 620MB image. Is the 20MB significant?
