Lavish,

You can override the default inventory file ( /etc/ansible/hosts ) with the 
shell environment variable ANSIBLE_HOSTS.

I use the EC2 dynamic inventory script 
( 
http://docs.ansible.com/intro_dynamic_inventory.html#example-aws-ec2-external-inventory-script
 
) like this:

$ ANSIBLE_HOSTS=/path/to/ec2.py python myscript.py
