Accessing client ip inside of the server implementation

[fabtrie]

To make my problem understandable, I will refer to the pubsub example server implementation.

What I want is to add the remote ip to the SubscriberHandle. I will need that later for establishing direct communication between two clients.

The issue is, when the SubscriberHandle is created in the subscribe function, I am not able to retrieve the remote ip. I just found being able to get the ip after the call to listener.accept().

What is a good way to access the remote ip when creating the SubscriberHandle?
