When you come up with the 'modified program' mentioned in this update process, you're just stepping backwards a step in the build process. You're not actually doing anything particularly new and exciting.I agree that stepping back in the build process by itself is not very interesting. If they had just diffed the .o files and linked at the other end, I would have agreed completely with you. The interesting part is the concept of feeding linker relocation info as hints into a more generic binary delta/compression algorithm. This allows for relatively simple decompression/patching at the other side, and also for proprietary software it doesn't require you to expose too much of the code's internals.
