根据@laberning 的通知，我现在使用了未记录的"流星连接.

As informed by @laberning I used for now the "undocumented" meteor connections.

您可以发布给所有订阅者的发布方法，例如:

You can post to all subscribers of a publishing method like:

// publish updated values to all subscribers
function publish_to_all_subscribers(subscription_name, id, data) {
  _.each(Meteor.server.stream_server.open_sockets, function(connection) {
    _.each(connection._meteorSession._namedSubs, function(sub) {
      if (sub._name == subscription_name) {
        sub.insert(subscription_name, id, data);
      }
    })
  });
}

// create stream publisher
Meteor.publish('stream', function(){
  // set ready
  this.ready();
});

...
// use publishing somewhere in your app
publish_to_all_subscribers('stream', Random.id(), {msg: "Hello to all"});
...

更新:查看示例 MeteorPad 用于发布、订阅和广播消息
