It's worth pointing that AFAIK no current Unix DHCP

AFAICS ISC's dhcpd has support for it; have a look at
dhcp-3.0.2/server/dhcp.c .  The function dhcp() marshalls commands out
to different functions, and calls dhcpinform() to parse inform queries
and send a response.

It _only_ handles inform if it's set "authoritative" for the network,

Of course what I _should_ have typed is that not current Unix DHCP *clients* allow use of DHCPINFORM. A quick poke around seems to show that's true for dhclient. No doubt someone will come up with a counter-example!
