I don't think Windows will use it. What we need is a Win32 client that will 
issue DHCPINFORM to get the setting and invoke "net time /setsntp" to stash 
it away, as well as starting the Windows Time service to use it.

For Linux, look at the ISC DHCP client. It has a script that gets all 
options and rewrites various config files. I believe the RH-provided one 
clobbers your ntp.conf if that setting is provided and an 
interface-specific setting doesn't disable the overwrite. Just checked... 
the package is dhclient (a subpackage of the ISC dhcp SRPM) and the script 
is /bin/dhclient-script. Browse that to see how it works.
