How about: the remote machine puts the file in the directory, then ssh's 
to the local machine which d/l's the file (rsync over ssh, or wget, may 
be better than ftp, but either should work in a script).

You can set up a key on the remote machine that is only allowed to run 
the rsync/ftp script on the local machine.

I suppose the above is a "mirror script" but I'm not sure what you mean 
by that, or why it won't work for you.
