I'm thinking of permissions settings similar to how you share stuff
through Samba.
You can share your stuff with guests (i.e. everyone, without
authentication), with all known users (stored locally) or with a
subset of existing users.
The list of users could be stored locally as RDF and then, similarly
to what Sebastian suggested, statements can be annotated with the
graph meta-data to specify privileges.

As for whose meta-data to store, would you like to go with a
high-level protocol, such as Jabber? So no low-level stuff?
Because, as I understood, the RDF repository is going to be exposed
through HTTP, so you could connect to anyone's repository and just
insert their address in the graph metadata of the statements you store
locally.
