A while ago I tried making windows' remote differential compression COM library work in a CLI utility like rsync.

You can install cygwin on windows. This will provide sftp, rsync and lftp which is awesome for doing rsync-like transfers on sftp-only chroot setups.
Also rsync does not exist on windows, for instance git bash has only scp AFAIK.
