I guess the phantom ID would be an ok stand-in for the nomad ID, except that anyone on the server can access the Phantom one, whereas the Nomad one would be limited to whomever the admins choose. I guess I look for admin intervention and regulation to help prevent abuse of the concept. One would only want conscientious players doing the nomad roles, people who will equip their ships appropriately, and behave like nomads, not go for vengeance harrasment and other fun-killing actions. Allowing people to conceal their infested human ships with human IDs would further give people room to abuse the concept by blaming any random attacking they do on their 'nomad resident.' If you require some overt sign be placed on your infested ship of its true nature you encourage more people to play into your role while allowing uninterested parties to avoid the situation entirely.
