TBO is an application aiming at making easy to create quick comics (a bit like comic life  which used to be bundled with Mac OS), it works by using vector objects you drag on the canvas and maybe edit a bit and then put some text on it.
celtx it is a "free" (not open source) software to create preproduction material for movies. It has an interface close to what I was thinking for CBS.
Plotbot is limited to screen writting but offers collaborative editing support.
