At my work, we have hardware keys that need to be inserted into printer ports (as well as USB keys) in order for the software to run.
It is my understanding that the early PS3 piracy required such a hardware key. So my question is, why aren't individual PS3's made out to be hardware keys for your PSN account? Do people really have practical reasons to log into their account from another PS3? I realize PSN is shared with the PSP, but bear with me.
Actually, maybe I'm all wrong, since it's via the internet, it's still a stream of data sent as verification.
Bah. mental masturbation, at any rate.
