[zeromq-dev] Peer ip address ?

hi I was looking for a way to find the peer/client ip address.
All of the replies I've seen so far say it is not possible to get the IP 
address of the peer in ZeroMQ.

The main objection for not providing the IP address seem to be that zeromq 
work on top of protocols which may not be TCP/IP.

The solution pointed by most of the people seems to be to figure out the IP 
address at the client and pass it as a part of the message.

I'm currently needing the IP address for logging purposes and in the future 
for filtering and routing.
Two problems arise :

1. What happens if you don't have access to the client code i.e. it is 
written by third party
2. Second allowing the client to provide the IP address could be major 
security breach, because if it is up to the client, they can place whatever 
IP they want, how would you know ?

How do you solve those problems ?  Unless zeromq, already have some means 
of getting the peer IP, the discussions about this were from 2011 ?

thank you
