I wouldn't call it voodoo <grin>.  I had set up email (courier-imap,
postfix) to hold user auth, so, I figured.. why not ftp?. I was
constrained to MySQL.

xinetd takes the call on port 20 and routes them to vsftpd and its conf
file. On logon, pam gets the auth request. /etc/pam.d/ftp has the
entries to look up the users in the db rather than system accounts. 

vsftpd has a vsftp_user_conf directive that contains a directory and for
each user if you want user-specific confs, which is nice.

Sample conf called by xinetd:

 ->grep ^[^#] /usr/local/etc/vsftpd/vsftpd.conf
