Dual boot is a nonstarter ... no pun intended.You mean this? http://www.android-x86.org/ xD

Last time i checked Touchscreen didn't work ^^ so that was a NoGo.
But still, i think that the pure "DualBoot" is to much work, better such a Console OS thingy that has both nativ but allows for easy switching with Live systems.
Seamless Integration would be best followed by some sort of VM window with at least copy past support and file access.
