Thad, We do something similar to what you describe you want to do. It's easier now than it was a few versions ago. What makes it easier is the fixed, floating licenses are stored in the data base.
Anyway what you do is create a DNS alias for your production server. You configure desktop clients and any MidTier servers to connect using the alias. Any internal connections like the email engine should also use the alias. Make sure everything works right. Install the second server to the DB instance. Make sure you do the installation as an upgrade. Like with the production server make sure that internal connections use the alias. Apply any server license while you have the fail over up and running. (You can get a hot stand by server license at no cost but you do have to renew it each year). If you need to switch to the fail over server, you shut down the production. Change DNS alias. Start up the fail over. Desktop clients may need to flush their DNS cache. In our case we also have several MidTier instances that are running on separate servers around the world. Users connect to the MidTier servers using a DNS alias defined with in the regional zone. The big thing is to test the stand by configuration at least once a year. You will be surprised at the little things hiding in config files that you forgot to change.

I found the white paper on load balancer configurations, but that doesn't cover what I'm looking for. Basically, we are setting up a secondary site to function as a failover (ARS stays down until needed), and I'm looking for the best way to configure ARS. We already have a mid-tier and replicated database set up, and now I need to put the AR server in place. In particular, I'm thinking about server names and how best to manage the configurations of those between the two servers (prod and failover). That's a vague question I know, (I'm just starting down this path) so a link to the white paper or any general advice is appreciated.
