[zeromq-dev] curveZMQ: authentication / ability to identify peers

I'm considering to use curveZMQ for authentication and connection security.
Unfortunately I haven't found a way to identify connecting clients. That
would be needed in order to see if they are authorized to do stuff on the
server, which seems to be a typical use case whenever authentication is

My questions are:

Would it be possible to extend the zeroMQ API to enable reading out
connection information which can be used for authentication?

The following might be quite useful in this context:
  - authentication method
  - peer IP address
  - peer verified public key
  - peer verified username

Are there any plans to implement something like that?

Would that be considered a useful feature?
