There is one interesting point in the original suggestion: Instead of
storing all chunks for a file together, it stores all chunks for a
revision together. That would spead up remote transactions, because
you'd not have to copy all the files to create their new versions
atomically, but instead atomically install one file. For reading, index
files are needed in either case.
