The first publicly accessible Moera naming server is now located at http://naming.moera.org/. It can be used for testing and development, so you don't need to run your own naming server. Moera node and client are now using this server by default.
The naming server does not use a blockchain yet for storing names. It is using a local PostgreSQL database, so there is no decentralization for naming servers for now. But the protocol supports seamless migration to a blockchain at any moment. Implementation of the blockchain for naming is not my top priority at this moment, all development efforts are concentrated around making publication and social features working.
I plan to publish other services (client, browser extension, demo node) soon. The goal is to make a working online demo for Moera that a regular user may play with.
