With a broadcast pub/sub design pattern, you can publish data from one controller (publisher) to any number of end-users (subscribers), all in realtime, simultaneously.
To showcase this functionality, we built a sportscast game cast app controller and end-user application using AngularJS and PubNub Pub/Sub Messaging. The controller can update editable fields and push those updates to the subscriber, which are immediately reflected in realtime across all connected subscribers.
We have a full tutorial, working demo, and all the code you need available here: pubnub.com/blog/broadcasting-one-many-angularjs-gamecast-app/
