Encrypting volumes or Amazon Machine Images will be difficult if your AWS setup spans many regions or accounts (AMIs). You’ll be able to distribute the keys using Amazon. Another, more secure method is offered here, but publishing them anyway seems pointless. Why expose a production key in a development account at the risk of being discovered? Why take the chance of losing a key you shared with a client? By default, you may copy unencrypted AMIs to other regions and distribute them with various accounts (in the same account).
