> There are perfectly legitimate reasons to put a network interface controller into promiscuous mode
Absolutely - for a long time it was the only way of adding multiple IP address aliases on a single network card in Linux for example (might hav been the same on other OS's - I don't know).
I once had someone imply we were trying to hack because our web servers had the network cards in promiscuous mode for that reason (of course this was a genuine concern - they could not verify the difference between someone innocently adding IP aliases and someone listening in on the mostly unencrypted traffic intended for the other servers connected to the same hub (I don't miss hubs...)
