} No.   The protocol doesn't allow for this.   You can't do it.

     I just reread RFC 2131 (Dynamic Host Configuration Protocol), and
I don't see where it specifies this?  It does say that the client
identifier must be used to associate a particular lease with a
particular client, but it doesn't say that additional information can't
be used to determine what address to give a client (I think this would
be an administrative issue).  Of course, a conflict resolution
mechanism is needed in the event that two different clients with the
same hostname try to get a lease.  But, I would see the ability to give
a fixed-address based on a hostname to be a highly desirable feature.
