It kind of funny when you think about it: Novell sold DR-DOS to Caldera specifically so Caldera could sue Microsoft (Novell didn't want to do it themselves for PR reasons). Caldera would reach a settlement with MS in 2000 and, later that same year, would use some of those funds to help finance their purchase of SCO.
It seems to me that, in a limited manner, Novell reaped what it sowed.
