If I remember correctly, isn't iRAM just a method of using RAM sticks as a solid state hard disk? Last I heard the boards carried a battery which kept the memory refreshed (so that it retains information when the computer is switched off), but it only lasted for something like ten hours. There is a youtube video somewhere of someone shutting down and rebooting XP in seconds using iRAM, but I can't be arsed to go looking for it right now.

I recall something about that myself.

I think it basically worked along the same lines as ReadyBoost on Vista and eBoostr on XP, fair enough your boot times might have been faster, but it still ended up using the RAM as a pagefile, so using a flash drive turned out to be far cheaper for a similar gain.
