Lorin, Diego, I wrote up a pastebin of setting up an example dnsmasq.conf file, setting it within nova.conf, patching linux_net.py (in stable/essex), and showing the example dhcp leases file which set custom values for the router, ntp-server, and dns-server using the dnsmasq conf and tags based on the network label field within the network defined within nova.
