How can I send a message to a particular subscriber in a channel using his subsriber id?

[Syed Tayyab Ali]

I want to use the subscription id of a user to send him a message. Something like this:

@channel.push(subscriber_id, data)

Could you be more specific about what your goal is? There are no terms like "subscriber" and "channel" used in em-websocket library.
