Certainly. For example. In E, the url-maker is an unsafe authority,
i.e., not a part of the safe scope. So by default, objects have no
authority to speak to any urls, or sockets, or anything associated with
the network. I can hand a particular url object to another object, or a
forwarder to a url object that has limitations such as, "only allowed to
write 1k of data to this url per second".
