Non Google Users Can Now Join Hangouts (for Work)+Google for Work
users can now invite non Google users to their Hangouts calls, via a link from Google Calendar. This feature even manages to do this without in any way compromising the privacy or security of the conference, by requiring the host to accept the new joiner (who is prompted to identify by name) before they can join.
I certainly hope they'll be bringing this, in some form, to non Work Hangouts as well. Google has generally been moving to tear down the walls of their service, at least for those invited by existing users, and this would be a welcome addition. #Hangouts
