There are many ways to peel an orange.  You may want to investigate
spawning subclasses with lease limits rather than specifically
allocating a specific pool for every customer (one pool with many
subclasses versus many classes and many pools).

The DHCPv6 software allows a host record (with a fixed address for
example) to be matched based on an arbitrarily supplied option field
name and contents.  This is not currently, but could trivially be
extended to the DHCPv4 routines.
