In a court of law in the situations I provided, would the difference you are trying to argue (a semantic difference IMO) be satisfactory to a judge such that the judge would eliminate CF from a lawsuit? Take your average judge - is "They're more of a cache" as an argument going to be enough to convince him/her to rule for CF? I think the answer is no. As with any case, "if you can find a sympathetic judge, you can win" so sure - there are judges who will choose to see a difference. But who wants to build a business strategy based on finding a sympathetic judge if/when a major problem occurs?
