Is there a way to get an rsync client to communicate over stdin/stdout?

I find two scripts: lsh (in Perl) and lsh.sh.

I don't think they do want I want.  The both look like remote shell
substitutes.  Am I wrong about this?

I want the rsync client to just use its stdin and stdout.  Any option
whereby the rsync client spawns a server via a remote shell program
will probably not work for me.
