Wow.... I'm not sure what to even think of this. I had to read it twice just to be sure I understood it. I'll be honest, I haven't a clue and would be inclined to say I wouldn't have believed it! Do PS3's use the same MAC address for both wired and wireless I recall? Might be some clue in there somewhere.
