Fixed MAC address for EC2 instances

Some software licenses require a fixed MAC address to exist.  Running on AWS EC2 the instance will get a new MAC address on reboot or shutdown or restart.  I way to ensure the new EC2 instance will get the same MAC address is to use an Elastic Network Interfaces (ENI).  ENI is like an additional network card that have fixed IP address (internal and external) and fixed MAC address.
