Capability based chat room

Does anyone have ideas for an authorization based access control (ZBAC) chatroom system. This means that all authorities in the system could be delegated, revoked, and communicated. Users could grant and revoke people the right to write to the users, and they could send someone else the grant right.

I don’t know the full details of ZBAC, but I’m gathering a team if you are interested.

One thing that I’m not sure if skype has or not is the capability to pass moderator ability to the next shift.
