Is there a way to configure OpenStack network without a NAT in Grizzly?

I'm looking for some way to config OpenStack's networking without a NAT using Grizzly. Each VM needs to be fully integrated into our current network, and should preferably use our own DHCP server.

Currently I achieved this in Essex by 'disabling nova-network': modified libvirt.xml.template, and defined a bridge to our network on each compute node interface. (http://dijks.wordpress.com/2012/07/06/32/)

I'd like to have similar capabilities with Grizzly, though ideally with a much 'cleaner' method.

Has anyone done something similar?
