I am a bit confused about the Google Drive Realtime API. I'm trying to build a whiteboard like app where users can collaborate in real-time. I figured Google's Realtime API would be perfect for this.
While the Realtime API can accomplish what I want to accomplish, do my users have to authenticate with their Google account to create a real-time document with my app? Do these documents created from my app have to be saved in their Google drive?
I was on a website called Realtimeboard.com. Their interface looks exactly like Google Drive. However, I did not have to login to my Google account to create a real-time collaborative document. Also when I create a real-time collaborative document using this app, the document is not stored in my Google Drive (obviously because I am not authenticated). Does that mean that they are not using the Google Drive Realtime API?
