rsync - Jan 2007 - how to rename remote directory using rsyncd

I'm looking for a way to use rsyncd to rename a directory in a module. 
I have worked out how to do everything else in the backup scheme below
using only the daemon services.  But I can't find a way to do the
directory rename without using SSH.  I couldn't find anything I could
use in the archives.  

In the backup scheme I'd like to use, each client has a module defined
on the server.  Daily, each client saves snapshots of itself into a
directory named for the date the snapshot was taken.  Previous snapshot
directories then hold copies of only the updated and deleted files.  The
steps I use are:
1) look for the most recent snapshot directory and save the name
(2007-01-06).  
2) rename it to the current date (2007-01-07).  
3) on the client, run "rsync -rt --delete-during --backup
--backup-dir=2007-01-06 localdir server::2007-01-07".

I can do the rename by running rsync through SSH as:
"rsync --rsync-path='mv 2007-01-06 2007-01-07 && rsync'
server:2007-01-07",
but I would prefer not to have to install SSH and user accounts on the
server.

If you name the most recent snapshot "current" instead of the date it
was taken, you won't need a rename, and the script won't need to do
any looking to access the most recent snapshot.  Or, you might
consider using hard-linked snapshots created with --link-dest instead
of backup directories.

You could have the daemon perform the rename as the "pre-xfer exec"
command of the module (see rsyncd.conf(5) for details), which is
conceptually equivalent to what you did with --rsync-path.
