The demand for this is going to be limited to service providers for the
most part. I get the impression (could be way off) that most people on
this list tend to use the ISC DHCP daemon for enterprise and educational
networks.  I'm not saying elevate the unheard requests (since logically
if service providers needed this they be saying so here right?) but that
the tendency in that vertical is to use one of the commercial vendors
most commonly Cisco's CNR.

Excuse my approach here, some of the responses from the list made it
appear that way to me.

I may do just that, as I said earlier we wrote some scripting around ISC
to do what we needed but things would be cleaner if the daemon had the
function instead of an outside program.  We looked at becoming a member
of the DHCP Forum, but the pricing was a bit much :(
