The dhclient daemon can preside over multiple interfaces at once.  So
each client state structure can represent a different interface.

To send/receive on the non-visible interfaces, I can use the myNet interface with a multiplex/demultiplex mechanism built into this interface (by an IO option) to send/receive any of the invisible interfaces.

I am really not sure I understand the question, but hopefully someone
else does.
