Thank You very much for developing this great module. I've been testing it for about 3 weeks and looking forward to see the projekt grow.
The module could be one of the most helpful expansions for Drupal 7 if it could realy restrict all viewing and interacting with roles that are locked for some other roles. Unfortunately I'm not able to help programing. I tested the module's cooperation with other expansions and irrespective of additional configurations it's still a problem to restrict profiles and users by roles.
I don't know if this is possible but it would be great if one could hide and restrict roles with this module related to accesses, views, contact actions and searches. The user id and the fast lookup as well as sending private messages or the search api are on my mind.
There is an module called "deadtome" http://drupal.org/project/deadtome that tries to hide users activities. Maybe there could be inspiration.
Thanks a lot
