Boot n900 from usb
 

Hi guys,
Just thinking, is it possible to install Nitdroid, Kubuntu, ICS and any other OS that can run from Maemo to a USB Stick and then boot from the flash drive/HDD.
Is it possible to make the phone read/configure the usb stick while it is booting? This came to mind when I was exploring features and commands in backup menu.
What do you think?
