See, if SCO does die, who's gonna get the UNIX ownership then?

Is this some sort of trick question? SCO doesn't actually own UNIX. The trademark is owned by someone else. The copyrights are claimed to be owned by SCO and Novell both, so if SCO dies, I'd presume that leaves Novell with an uncontested claim. All SCO really owns of UNIX (as far as I can tell), is the right to sell and collect license fees for Novell, some documentation, and some historical legacy code (to which they don't necessarily own the copyright, so really have no control over).
