OK I got the skinny on this.. They are sending me the SDK so that I can try it out. I will post feedback here.
Apparently it works somewhat similarly to XP's built in hibernate feature except that it can be configured to resume into the exact same state every time you power on.. IE every time you boot up, you boot into a fixed system state.. the system reverts itself to this state on every startup so that stuff like loss of power, etc are not a problem for it.
Support is available for XP Pro and XPe (embedded)
I will be getting this probably next week and will start seeing how it works immediately!
