Peter, We also use the same server group name across environments and use host files on our local machines to administer each environment when needed.
In addition to the diagram below, I like having a dedicated mid tier to the admin box outside of the user load balancer as well. It helps since a lot of forms don't display properly in the WUT anymore. Also, I'm assuming you're not allowing unqualified searches on the user facing boxes. I've had instances where a user needed to run a query beyond the limit we set so having a mid tier pointing to the admin box allows for those one off requests as well.
