I can see some benefit in propagating local endpoint information
(from getsockname() and/or gethostbyaddr()) to the policy daemon,
because it is like the other policy attributes: it is dynamic state
that carries information about the context of a message delivery
request.

I can also see some benefit in the ability to specify a list of
user-controlled (name, value) pairs that get to be sent across with
each policy service request:

<policy service name>_attributes = hostname=$myhostname foo=bar

But I see little benefit in a patch that adds support for a hard-coded
hostname attribute only.
