It shows you how to combine the daemon-accessing syntax (which it sounds like you aren't using) with the -e (--rsh) option to achieve an ssh daemon connection.  If you want to force this for all ssh access to that user, you need to look into using ssh forced commands (where you either force the command "rsync --server --daemon .", or you force a script that checks the $SSH_ORIGINAL_COMMAND and outputs an error if it is not that).  See also the rrsync script in the support directory that offers a non-daemon way to force an incoming rsync into read-only mode (using a forced "rrsync" command).

You're absolutely right; my quote in my original post came from that part of the documentation, but I completely misunderstood it; I was trying to use daemon features with a standard server connection.  I'm going to give it another try and see if I can get my idea to work properly.

Thanks for pointing out that I'm an idiot (seriously!),
