In a Rating 3 bit of gear - you can only run rating 3 programs. So, run 6 programs on that node, and its a bit... well rating 1? So the agents have 2 dice?
Be there as a hacker, and you have 1 (from your program) 4 from your skill group, 2 from hot sim, more from cyberware... (+1 from some cyberware brainboost that costs 0.75 essence = 8 dice.
Making in the best case the Hacker utterly win against agents.
In a more typical senerio, (Responce 3 device) the Hacker has 10 dice, against the agents 6. Still a massive advantage.
I think, anyway. (I'm not sure that Hackers or agents running on a comlink don't use that comlinks responce) Agents sent in as "drones" definitly use the devices stuff.
