Honestly, I am just trying to suggest ways everyone can can contribute, in combat or the Matrix or whatever, doing what they are built to do.
I'm not specifically hung up on hacking cyberware, it was just an example of a possible quick battlefield hack.
My concern is that currently, anything a hacker does in a firefight related to his specialty takes multiple rolls and GM attention, and if successful sometimes gives the hacker TOO much control. You spend potentially multiple rounds rolling dice and afterwards you completely own the system.
There's no provision for quick single roll hacks that create a temporary effect. Even the closest equivalent in 4e, spoofing, requires multiple rolls as the hacker needs to locate the node, figure out the access ID, and then spoof commands.
The idea is to create more immediacy to the hacking process by providing a way to toss off a quick temporary hack that can be executed with a single roll, is resisted like a gunshot or spell, and fades soon afterwards. It doesn't have to be a cyberware hack, it can be something like activating a road pop-up barrier during a vehicle chase, or shorting out the lights to provide concealment, and the like.
Similarly, we shouldn't have folks going to get drinks when it's time to hack a mainframe. The sammy should be able to at least assist, perhaps in a similar way he would if he was pulled into the astral. He'd be nowhere near as good as the actual hacker, but he could help, as opposed to sitting there watching the hacker's comatose body and twiddling his thumbs.
