I think the storage node/proxy node distinction if a good idea, because
they have different requirements in bandwidth, disk and CPU; check:

http://swift.openstack.org/howto_installmultinode.html#basic-architecture-and-terms

The minimal production environment could be 3 storage nodes (different
machines, because you need at least 3 zones if you're going to have 3
replicas), and a variable number of proxy nodes (at least one!).

You need to host the authentication service somewhere (if you're running
just one proxy, that can be the place).

I recommend you reading:

 http://swift.openstack.org/deployment_guide.html#deployment-options

You don't need VT support on any swift node.
