For the use we do in git IMHO it would seem appropriate to look for algorithms used in the field of filesystem compression, where decompression penalty is a design goal. I know very little about this but I think among kernel people, expert and competent hackers should not be difficult to find, given that compressed filesystem are around from many years under linux/fs/ directory.
