Generally one implements notifications by listening for events on specific models but if one wishes to have a single global message interchange, it could be done as follows:

var pubsub = new Backbone.Model;

View1 = Backbone.View.extend({
  initialize: function(){
    pubsub.bind('custom event', callback);
  }
  // ...
});

View2 = Backbone.View.extend({
  // ...
  foo: function(){
    pubsub.trigger('custom event', data);
  }
});

or the reverse if one wished to publish events from models or collections.
