I'd like it if nobody realized what Vane was doing for a while. Especially since he'll be moving very slowly and doing everything in his power to wipe his tracks so that nobody can trace his tinkering back to him. In the event that they did find traces of his tampering, it would actually lead back to his AI which has been integrated into the system.

I would, however, like it a lot if they eventually had hacker battles once Vane really gets the plot ball rolling. :)
