1) yes
2) find a live cd that can load live cd to RAM which already has partimage on it
knoppix has cheatcode...toram but now-a-days is a dvd so you might want to d/l an earlier cd edition?
systemrescuecd has partimage on it.......and cheatcode is ............docache............. as per
http://www.sysresccd.org/Sysresccd-m...ing_the_CD-ROM
this looks like the best option as it only needs 400 megs of Ram.
grml has bootcode grml2ram...but does it have partimage?
but you need to check exactly how much ram you have for each computer.
3) the tools you ask about...........the tools stay on the live cd....no need to install them into the hard drive partition image.
