Meanwhile, back to rootkits and DRM...
If Sony is suicidal enough to install hidden rootkits on users' HDs that can still be detected but hardly removable at all, don't you think that means it's planning hardware lock-ins as well in the furute?
The Playstation 3 will probably ship with a HD unit, with a GNU/Linux system preinstalled to provide emulation of PS1 and PS2 games "in software and hardware".
Don't you think this could also mean such rootkits might be present BY DEFAULT on the HD, and any tampering with these could mean lost functionnality for your PS3, as it is the case currently with the XboX (tampering with hardware means your console will be banned from XboX Live FOREVER, even if nothing actually occured)
With hardware lock-ins, it will (most) definitely impossible to remove such a piece of scumware from your HD unit, even for skilled techs...
Dudes, watch out for anything with SONY on it, keep your computers safe, this scheme surely isn't restricted to music CDs, probably doable on anything with a HD (computers, consoles, huh...iPods?)
