I don't see there is any need for the client to open
another socket waiting for the server notification.
Since an IPP connection is persistent, the server can
notify the client over the same socket any time. If
a notification needs to be sent after the session is
closed, the server can wait until the same client
opens another session, provided that the server can
uniquely identify the client. For completeness, a
time-to-live for the message may need to be defined.

What this means is that if the client is ever interested
in any notification from the server, it should remain
online or check back with the server later.
