Honestly, why bother? Cyberware has a signal strength of 0, right? Are you saying that a hacker is going to be able to get right up next to the street sammy and hack his ware without him knowing? The most common point of attack is, and always will be, the PAN. So load up on Firewall and IC, and be done. If someone is bound and determined to hack you, they will. The most anyone, even another hacker, can do is slow them down or fry their brains as they make the attempt. Pay attention to the basics, and leave the high end stuff to your party hacker.
