There's this internet frontdoor developed by someone here one the University
(wswietse at info.win.tue.nl), which could fullfill your needs.

It's a small program which replace an original inetd forked deamon,
logs the session and from where it was originated,
then checks if the site is authorised to do so, if not it aborts the session.

This not only for ftpd, but all: fingerd, rshd, telnetd, .....
So you could do real nice things with it. 

On           ftp.eb.ele.tue.nl [131.155.20.25]
you can get  /pub/apollo/frontd.10.3.tar,Z 
(Note that is changed to be used on Apollo systems, but that mainly concerns
 the makefile.)
               
You could also go to: svin02.info.win.tue.nl
and get		      /pub/host_deny.tar.Z
which would give you the one made by the original author.
