So my position has shifted in the time we've debated this, but what I'm thinking now is that this probably isn't unintended (or at least undesirable) in the minds of the rules team, and we don't need to come up with any sort of etiquette or house rules to manage it, as I'd originally suggested. I'm now suggesting that this sort of thing (targeting an unhackable target with a Hacking attack) is an expected virtue Holoprojector. But then again, who can know the minds of our favourite Spaniards, eh? Dunno.
