I think a pod is a host, like wordpress.com is a host of WP blogs, hence a database per pod. A seed is an individual user account. The way I understand it, each seed can be encrypted so that even the pod owner can just look in the database. The really interesting bit comes from key and information exchange between seeds. I agree it's going to be hard to explain all this succinctly to users. Theoretically, the goal is secure and decentralized social networking. One use case would say, a friend on another host can see your photos, but no one else on that other host. Can this ever be done in a foolproof and secure way? I can think of a lot of different things that can fail - malicious impostors, users setting the loosest security, revocation, but it might be good enough for a vast majority of users.
