Would like to move my Eprints instance from a campus-only resource to a world accessible resource.

To facilitate this, would like to offer the ability to control the visibility/access/searchability  of certain deposited items.

I am envisioning access based upon department-only, campus-wide (by IP address) or world-wide access groups.

Where do I begin?

I see plugins for OpenID, blackout, reference to OneSharePerms but not seeing how to put it all together.
