I don't think this option would be useful to enough people to justify
including it in the official rsync (of course, the final decision is
Wayne's), but by all means make your own version of rsync with the
option if it does what you need.  Another approach would be to write a
script that runs the custom checksum program on the source and
destination files, determines which source files need to be copied, and
passes the list to rsync with --files-from .
