Is it possible to use this for other applications such as: XP install 7 install UBCD Memtest x86 ect... It would be nice to have a number of images on a USB stick and then pick them from grub. Also, it would be easy to upgrade the versions of the ISO's because all you would have to do is replace the ISO with the most recent version (and maybe modify the bootloader, if the image name changed). Not sure if this is capable of this but if it was that would be awesome.
