i have worked this out
wouldn't you just be able to use a "ram/drive tool" on the desktop of the "ram only win32..." booted machine....
that tool would just save an image of whatever other desktop tools you installed into it .........thus it would save all your settings and everythig.....then you would put that image on a pen
you could have several images or such like
hmmm....i can't see why this would not work for persistance
