Interesting.  I'm not too familiar with iptables, but based on that tip
and what I've read from the man page, I should be able to do this for a
webserver:

    iptables -t nat -A PREROUTING -p tcp -d 192.168.1.20 \
      --dport 80 -j REDIRECT

This should allow my machine to accept packets destined for the virtual
IP (on port 80) and redirect them to localhost.  Did I mess anything up
there?

Just a couple of questions come up here:

  1) Do I still need to enable ip_forward?
  
  2) When the server replies to the client, will the reply be sent from
     the proper virtual IP address?
