I wouldn't go that far. Xmodem was designed for CP/M and worked just fine for that since CP/M saved files in 128 byte chunks. In that case, Xmodem did in fact leave the data alone. It's the fact that folks decided that Xmodem was a neat thing and tried to adapt it to other environments that has caused the 'problem' with up/downloads….not the protocol itself. It was never designed, nor intended to be an all purpose protocol…it just worked out that way.
