You are correct. I still feel comfy, however, reason being I see quite a bit of distance between a working prototype and “seeing no reasons” why it can’t be done someplace else. As for “blue pill” not relying on bugs - that’s ok. Exploits still need to rely on operating systems processes, as well as business processes. Those are readily accessible (and correctable) where open (and where companies have a head start). Note that the Sony rootkits were available for Macs too, its just that you had to jump through a lot of hoops to get one on in the first place. Again, process, not bugs.

Rutkowska stressed that the Blue Pill technology does not rely on any bug of the underlying operating system. “I have implemented a working prototype for Vista x64, but I see no reasons why it should not be possible to port it to other operating systems, like Linux or BSD which can be run on x64 platform,” she added.
