Forum OpenACS Development: Response to Software Development (Bugs, QA, etc) and OACS

The comments in the 3.x sql file led me to believe that it was to decide if a user could even see a module in the listing.  I think it was a simple answer to the question "What if we write mostly open source software, but we have a couple of modules that we need to keep under wraps?"... not intended to scale to more than a few special people who maintain the module code.  ACS Perms would allow some much more complicated scenarios.
