TAO has support for policies as part of the tagged components. This is used for example by rtcorba. This is now handled in the RTCORBA specific rtstub, but for ziop we have also policy values that need to be transferred from server to client. we can of course do this with a ziop_stub, but that doesn't seem a way that is maintainable for the long term. we need a more intelligent default stub that works together with some more smart policy classes. the policies that have an exposed value need to have a method to get the real effective policy, then each policy can sort out the real value instead of the rtstub doing that
