community board

I came across this ReQtest Agile board software and wondered whether anyone has ever tried it. If anyone can let me know, based on your knowledge with this and other software, what you think I'll appreciate it.

The idea I was looking for in different CMS, but didn't find. I also looked a lot of drupal modules and didn't find suitable module.

General:
My idea is to create a special access control system, that support flexible and full restriction methods to author's content.

Description:
This system should meet next requirements:
1. Access system can be applied to all types of content: menu item, category, topic or a single post
2. System should have next restriction types:
- Allow All - allows to read, edit and comment content
