Everything is crackable as i have already said. time is not a factor so much as customer experience. The fact is most companies spend well to much on weak software lockdowns that infuriate the end user and get cracked eventually. Sure there are systems like the one mentioned but is it really nessecry. Customers will either buy it download it for free or not use it at all and the only ones that matter are the ones that buy it so don't annoy them with illusions of security that make thier experience a bad one.
