[zeromq-dev] Indentify message sender

[Justin Azoff]

Additionally, at least with czmq, the zap handler also adds the zcert
metadata to the socket metadata.  So if you had this in the zcert
file:

metadata
        can-read = true
        can-write = true

you should be able to access the 'can-read' attribute on the message
metadata in the same way.
