Initially, at least, I'd guess that this NVM-HCI thing is all about
built-in flash memory on motherboards, to hold the "instant-boot"
software that hardware companies (eg. ASUS) are rapidly growing fond of.

At present, that means a mostly read-only Linux installation,
though MS for sure are hoping for Moore's Law to kick in and
provide sufficient space for a copy of Vista there or something.

Yeah... instant boot, and "trusted boot" (booting a signed image), storage of useful details like boot drive layouts, etc.

I'm sure we can come up with other funs uses, too...
