It is definitely possible if you are willing to use separate 
ports for different machines.  Using only port 80, I don't 
know.  One idea I had while thinking about this was the 
following: Why not try writing an ipchain/iptable 
forwarding rule using the -d option set to the hostname you 
would like to forward?  The format is the same as the -s 
option, and is described in man ipchains/iptables.  Since 
the man page warns against using a name that would require 
a reverse-dns lookup, I suppose that it would have to be in 
your hosts file as well.  I don't know if this will work, 
but there's a chance.
