1. Create two user accounts.
2. Create a copy of the ArmA3 dedicated server for each user account.
3. Create a system service, such as through FireDaemon, that launches each dedicated server under its corresponding user.
4. Confirm that only one of the servers will run properly and generate log files. The other will use about 100 MB of memory and seemingly hang. Shutting down one of the servers allows the other to start up.
