DAO is a whitelist system that implements the udao.DAO interface. It can allow a trusted list of addresses to share the administration of realms that are designed to be managed by "DAOs". It's not a DAO per say. But makes sense to be used to bootstrap a realm until the DAO can replace itself with a really decnetralized autonomous organization. Asan inception. It's also useful for people who manages multiple keys, like on different computers so they can simulte being a single entity while managing several addresses.
