live cd

I have noticed that there is an increasing number od live linux cds that let you store your home directories on disk, usb, or floppies. This gives one the potential for making a protable sysem where you carry the operating system on cd and your home directory and personal programs on a usb drive or other portable storage. Some live cd's such as puppy linux let you use a cd-rw which is a neat way of acieving protablility.
