If the Amazon account has more than the default 5 Elastic IP addresses, it could be useful to have mr.awsome automatically create a new Elastic IP and associate it with the new EC2 instance, rather than needing to hardcode these IPs beforehand in the .conf file.
How would you associate it after a restart of the instance? Elastic IPs only make sense if you need a fixed IP and then you need to put it into the config anyway.
