Interesting thoughts, but a quick look in Google seems to tell me it is for Vista buffs?
HyperOs has been flogging the idea, using large amounts of RAM with their software going back to Windows 98SE. They called it Hyperdrive.
It was also a time when malware thrived and the idea of booting into a system using RAM instead of HD, which erased everything on shutdown was fine say for Internet only.
It was unrealistic when OSs and applications soon involved several Gb at any time.
HyperOs is still selling seriously expensive hardware where the effect is the same because the hardware (as I understand it) is bristling with lost of DDRAM and is used as a "virtual HD."
Me? .... I have paid lots too much money over several HOs upgrades, to have a multi-booting system which behaves like a smoother version of Acronis or Ghost.
