Yes - you don't need to run ssh to use rsync in daemon mode.  The
authentication mechanism uses a challenge/response so the password is
not sent over the wire.  The rsync data sent after the authentication
suceeds is not encrypted, which sounds just what you are after.

If you read the manual page for rsyncd.conf, look at the sections on
the 'secrets file' and 'auth users' parameters.
