Push message to resource owner
I get some confussion to understand how push message to resource owner. Let say a user want to do a long running process job to app. The app will queue this and tell the user when the job finished.

We can persist a job with owner information and then when the job finished, the app will emit finish event and tell ZMQ to send message to client. I can use token or cookies based authentication but i have no idea how to send the message to the appropriate user. :)
