John,
 
What do you mean by does it do anything?  Currently all three projects are working and we are in the process of finishing new verisons. ;)

Check out http://www.bsdshell.com 's EtherFirewall project.   It will allow you to maintain Mac addresses with your IPFW rules. 

Now regarding the hostname to ip address conversion for firewall rules.  I have a feeling it is translating the IP address at the time of entry so this is not really going to work for your round-robin situation.  EtherFirewall is the clear choice for this.

Good luck!
