So you are interested to map host-ip to authenticated user on that host, 
correct?  I think you should be able to produce a login script that 
initiates an ssh connection to authpf, which in turn adds required rules 
to the firewall.

Note that anything that relies on host-ip as a security feature is doomed.  
Especially in LANs an IP is easily spoofed.  So unless you have a proxy 
that can do further authentication, you can't be sure you get what you 
ask for.
