1) I don't understand how this copy protection works? If I want to copy it on to a second computer, or a mates computer, (not that I will), I'd just ring up and get a second unlock code saying I'd changed computer. How do they know any different? Also, if VRPC gets in the PD, surely anyone could ring and get unlock codes pretending to be people who really own VRPC?
2) If I change the MAC address of my cable Network Card, VRPC still works, so I can't see it is tied to that.
