Probably something in the vein of a DHT. There is still a lot of progress that can be made in that area, in terms of performance, content addressing and cooperative/adversarial search strategies though. I pick on DNS because it's an easy example of another thing you have to manage hosting your own content. Also, domain names are a hot mess and people mostly prefer to have identities ala Facebook, which could easily built into a decentralized protocol.
