Reading http://zguide.zeromq.org/page%3aall#Transient-vs-Durable-Sockets, you can only get the identity of the socket you're working with... not the socket of any peers you're connected to.

This being said, just build the sender information into the message. This should be trivial to do (either with a UUID or specific name per client).
