OS X Panther FTP questions – anon and symlinks

I have a need to create an anonymous ftp swap space on an OS X Panther server, my plan to keep it clean is to have a cron job run nightly to delete all the files in the FTProot. However I don’t want to allow regular users to use FTP; I would like them to use SFTP or if I can’t, force strong authentication. My two questions are — can I enable ftp for guests only in a chrooted environment without allowing ftp for regular users; and how do I keep the ftp service from putting symlinks to shares in the FTPRoot? I tried creating a custom FTPRoot and pointing to that with ftpaccess but the symlinks got recreated anyway. I also compiled and installed pure-ftpd but am having less luck getting that to do what I want than with the builtin xftpd or ftpd.

Thanks for any help!!
