I think what he meant was also copying the reading part from USB / LiveCD to 
the RAM drive and let it run from it. So that you can actually remove the live 
media. 
This is achieved by Ubuntu based distributions by using the toram bootoption. 
It copies the live-media to the ramdrive and runs from it. 
But you are right. Changes to the live system are always (except you use 
persitency) written to the ramdrive

It is already implemented aswell as almost every feature of puppy except for 
writing changes to the live system to a cd-rw or overwriting another session 
in cd-r.
