The worst thing about organizing an online meeting is squabbling over platform.
As of today, you no longer need to have a Google account to join a meeting Hosted on Hangouts - just a link.
It should: Last month Skype did the same thing - adding a URL-based invitation system that allows guests to join a conversation without having an account.
Google's version will place the link directly in calendar-based event invitations, and give meeting organizers a chance to allow / deny entry to the guest when they try to join the meeting.
