Notci shall have a minimal feature set on its own and will depend on clients to implement more advanced features like search, tags and groups.
Atleast there will be a register of nicks and their public keys. All messages and posts will be encrypted, at the moment it looks like OpenPG will be used for this, and based on the users choice publicly readable or not. And addition to that, all shared date will have a limitied time of life, to ensure the exchanged data needed to store don't grow endless and become a burden for the node owners. Burden hmm, ah yes, I will try to keep it mobile device friendly as possible.
