I would like to use this module only for the View permission, so that users can determine who can see their user-submitted content; but I don't want to grant them the permission to allow anyone else to Edit their content, and certainly not for others to delete it. Of course I could prevent this by not granting them the rights to override permissions for a node, but that would kill one of the most useful parts of this module (while still providing the ability to control the overall View permission by content type)

Specifically, this module needs a main configuration menu for Administrators to control (via a new "administer node privacy by role" permission) which permissions (View, Edit or Delete) will be made available to those who can see and override the View/Edit Permissions. Of course you could also take this feature request in a slightly different way by including a similar control in the content-type edit form instead of a central administration form -- not sure which would make more sense.

I may need to hack the module in the meantime unless anyone has any suggestions...
