Jon, I have a small script that runs on the clients that runs every hour and updates a ldap database with the mac address, ip address, and the client name. Then on the dhcpd server each hour I create the dhcpd.conf file so the name is always mapped to the correct ip. This works well in my situation with several hundred laptops that are hopping around between subnets all the time.
