I didn't say anything about unauthorised access. Both Sony and Microsoft want to have these consoles develop into more than just consoles, poor men's PCs as it were with authorised programs. I think Xenon with three times as many PPE cores and double the cache is better suited for that role IMO and don't forget all that Mac software out there now that already runs on PPC hardware that could be ported.

Due to the Sony Cell hype I think people are being concerned about the wrong disruptive hardware ;-).
