[GRLUG] Connecting DHCPd and bind

I have a box which shall be running BIND9 for a caching DNS server,
internal zone name provider, and VPN view provider. It will also be
running dhcpd to my local network. I'm somewhat familiar with dnsmasq,
but I don't want to use dnsmasq for DNS.

I would like a DHCP/DNS arrangement that:

1) provides hosts with an IP address after checking to see what IP the
host should have, based on the DHCP client's stated host name.
(Though, obviously, this should be able to be overridden by a static
MAC/hostname or MAC/IP configuration line somewhere)
2) Updates the internal view so that other internal clients can
resolve new hosts by their given names.
3) I can expose the internal view to other views (such as requests
coming from VPN; a firewall at the router will block traffic from
unblessed hosts.)

The part I don't get right now is how to reliably tie DHCPd3 and BIND9
together (i.e. I don't want to make a change in one place, but
discover I've forgotten to make it somewhere else). Can someone clue
me in with a few different options I can follow up on?
