Well I use it that way, too. But with persistent storage (pupsave). I don't deceive myself I'm getting a read-only installation by doing that.If people want to install a live CD that is their lookout. I'm still intrigued enough by the possibility of a live-CD OS to be sad enough to want to use it that way.
Pizzasgood has a solution to ease the pain of going full read-only. IIRC not everything configured gets copied over in a remaster though.
