TC is now such a broad concept that it's nearly useless. The wikipedia page does make it sound like both Bitfrost and drectory permissions would fall under the TC umbrella. But so would AppArmor. And hardware virtualization extensions. That doesn't mean they have anything in common with each other.
We can at least agree that FairPlay, CSS, and Microsoft's incompatible flavor du jour are examples of DRM, yes? defectivebydesign says that Tivoization is a form of DRM. And Hasp HL claims to be DRM. Bitfrost's ultimate behavior is basically the same as these technologies and has only the most superficial resemblance to directory permissions. That's why I really don't think it's a stretch to consider it DRM.
Maybe you could point me to an authoritative definition of DRM? The definition at the top of the Wikipedia entry clearly includes Bitfrost but, alas, I'd hardly call it authoritative.
Perhaps the media is subverting the meaning of DRM like it did with hacker? At this point, though, I'm afraid the cat's pretty far out of the bag.
