Thanks, Bill!  I finally got around to finishing up some checksum
improvements and have added support for xxhash in the master branch. The
latest version in git now picks the best checksum algorithm in common
between the client & server version, and will support future checksum
algorithms being added without the need for a protocol bump.  It also
supports a new RSYNC_CHECKSUM_LIST environment variable that allows the
user to limit what checksum algorithms they want rsync to use (in addition
to the already existing --checksum-choice=FOO option that forces the
checksum choice).
