You could use a `local_action <http://docs.ansible.com/playbooks_delegation.html>` to shell out to some command that generates IDs [1]. This technique is often used to generate passwords in Ansible plays [2,3]. You could generate hostnames in the same way by simply restricting the alphabet of generated strings to something like `[0-9]{3}`.
