It would be great to have a NoReaders field type that can be used to stop specified user(s)/Group(s) being able to access a document. I have been asked often if it is possible to stop some users from accessing specific documents.
In some cases it might be possible to implement it through a new group and a readers field, but not always.
Having a NoReader field type that allows users, groups, roles to be specified would make this easier and allow us to build application functionality around it, i.e.
- allow users with specific roles/privileges to add a user/group/role to the NoReader's of a document
- allow an view to be defined that lists documents where NoReaders != "" so application admins can keep an eye on such usage
