If you're accessing the daemon through a socket, then it automatically
only allows access to modules.  If you're accessing it via a remote
shell (e.g. ssh), then you need to configure the remote shell to limit
what the user can run.  See the rrsync script for an example of this:

That script is written to enforce control on a non-daemon-using rsync.
You'd want to change it (which would simply it a great deal) to only
allow the user to run the command "rsync --server --daemon .", which
would disallow any non-module use of that login (see the script's
comments for a general explanation of how to configure ssh to add a
restricted command to an authorized key).
