Wow! Google has a new contact manager that may enables sharing contact lists across organizations

This is the Google announcement:  http://googlesystem.blogspot.com/2015/03/google-tests-new-contacts-interface.html.  Copy and paste that into your address bar.  It is an early March announcement, but I was just "automatically upgraded to the new version.  It looks like, using the Google+ environment, you can create a "friends" group, which might be an organization you belong to (eg Barbershop, Church) and share the addresses between all that are in the group.  It looks like Google is saying that your address list for your organization will be up-to-date for all people in your organization!  Has anyone tried it?
