Ken Rickard on the Workbench Access module
Ken Rickard (aka agentrickard) talks about the Workbench Access module, which provides editorial access control to content based upon hierarchal groups using either taxonomy or menu. It can be used along with the editorial suite of other Workbench modules, but it can also be run as a stand-alone module without any dependencies. Workbench Access can control access to the editing of content, but it doesn't provide any access controls for viewing content. Rickard talks more about some use cases that they're using Workbench Access and some future plans for it.
