I've been working up a patch to submit for simple_access. Basically, I'm trying to achieve the concept of letting a student say "only share this node with the faculty ", but of course the students aren't and shouuldn't in the faculty role. I'm sort of stuck. I had no problem modifying simple_access to display all the groups, but reading the API documentation, I'm unclear as to whether there's a hook that will let me override the permissions behavior defined in the node_access table. If I read correctly hook_access only applies to nodes that I define in my module, but I was looking for site wide behavior. Can hook_node_grants be leveraged to do this? It's a little unclear to me from the docs. Is there a different recommended strategy? Dave
