Can I set up an OpenStack cloud with just two physical servers?

I have two 1RU pizza boxes with some quad-core procs and want to follow the following guide: http://docs.openstack.org/grizzly/basic-install/apt/content/basic-install_controller.html

Pretty standard stuff, KVM for hypervisor, local storage in each (though i could probably use more)

However, the example gives three physical servers. My plan is to only use two servers, but move the network service into the "cloud controller", essentially making one server run all services, and the second server is just a compute node. I'll also likely move most of the hard drives out of the compute node to give the "main node" which has the storage services installed as much storage as possible, since the compute nodes will only be used for their RAM/CPU.

Does anyone see any problems with this approach?
