I think, there is no point in using rsync, as there is nothing to
compare against on the remote side (and I've doubts if rsync will be
happy with a "file" that isn't seekable.)

As rsync uses SSH nowadays, I'd do something like

        scp LOCAL-FILE remote-host:FIFO

But, I'm not sure if scp is happy with a FIFO on the remote end.
A fallback could be

        ssh remote-host 'cat >FIFO' <LOCAL-FILE
