does it make sense to run rsync over ftp (curlftpfs)?

With --append, rsync will append to the destination file.  With
--no-whole-file --inplace, it will write only the changed blocks, but it
will read the whole file first, which may defeat the purpose.  Rsync is
at the mercy of curlftpfs as well as the FTP server to perform any
partial updates efficiently; I don't care to research their capabilities

The main reason to use rsync over an impoverished virtual filesystem
would be to take advantage of rsync's non-performance-related features,
such as filters.
