How about reserved leases ?
A reserved lease acts the same as a regular lease, except that it is permenently tied to one client even after it expires. IIRC you simply need to add "Reserved" to an existing lease (or add a basic lease skeleton with Reserved) - either by editing the leases file or with OMSHELL.

Because it's now a regular lease, it goes through the normal lifecycle with DDNS updates, etc.
