Little point arguing any more about the rest of your post since we're just going around in circles. However, on the points above, I'm not referring to PSP as a way into PS3. I'm referring to Datel signing their own executables to run on unmodified hardware. In short, they have replicated Sony's private key for creating encrypted software. Nobody else has done that, certainly not unpaid researchers. It won't help on PS3, but puts their operation on a different plane to the homebrew hackers. While Datel may well be considered to have leeched a lot of work from them, I've seen their factories and labs, spoken with "Mr Datel" (one of the richest men in the UK btw) and his engineers and they are a formidable operation.
What I mean is that, if Datel, with his solid operation, has only figured this out after some unpaid hacker spends a few months fiddling with the PS3, I'm not holding my breath on them actually coming out with a product. My suspicion, instead, is that this isn't new to Datel. (I'd even guess that this isn't new to Sony, either.)
