No, each node does not need its own NIC. It all depends on how you 
implement the ethernet interface in the emulator...
You could just have all of them run over the same NIC, and that NIC act 
in promiscuous mode. That way you get packets to all the emulated NICs, 
and then you sort them out in software. Takes a little more processing 
power, but might be a good idea for other reasons anyway. And sending, 
creating your own ethernet frames is normally just fine nowadays too, so 
the outgoing frames looks just correct as well.
