While I have some sympathy for privacy addresses for outgoing
connections for WWW browsers accessing random global destinations,
some specific connections will identify you anyway and benefit from
a controlled address. E.g., the Windows LPD *client* should use an
identifiable address; mostly you won't get printing authorization 
without that, and it's oranization internal anyway. Similar for
remote login protocols like ssh, which often are restricted to a 
small set of allowed addresses in addition to other restrictions.

This is not something that can be decided at the "this machine is
a server" - "this is a client" boundary; the same machine will want
to act identifiable for some application and anonymized for others.
