Yup.  Dat's me.  Essentially I take Cool's per-object security model
(each object and method determines its own security criteria), and
provide APIs for easy testing of the inheritance tree of the
method-caller and message-source (who originated the event) as the
basis of determining validity of access.

I don't impose limits in the server.  The DB may model various limits
and attempt to impose them on the rest of the DB.  As such I put
damned near nothing that is game-oriented in the server proper (ie the
server has no concept of containment, command parsing, placement, or
context).  Everything devolves to the DB.
