I did a little research, and ran across RFC 3203
(http://www.ietf.org/rfc/rfc3203.txt), which was approved earlier this
month.  It describes the DHCP FORCERENEW message extension, which does
exactly what Brian is asking for.  Now we just have to wait for it to be
implemented in the various DHCP servers and clients.  Preferably after
DHCP auth (RFC 3118) gets implemented.  :)
