Perhaps a Copy2RAM option could be added to the grub menu like on some Linux distros?
Yeah, I like this idea. I've been working quite a bit with this with rather large WinXP disk images (i.e. > 2GB) . Loading the images into ram with Grub is pretty painfully slow, but once the image has been loaded into RAM, the boot up time is only a fraction of what it takes to boot a hard disk based WinXP system. I'm talking like 20 seconds vs. 2.5 minutes.
I've just started playing with Icaros in Virtualbox and it was easy to get it going. (Tried Broadway, but couldn't seem to get networking working. I'll have to look into that some more.) I bet the Icaros light package would load pretty nicely into RAM and run. Maybe I'll take a crack at it.
