It would actually be huge if an industry such as the oil one would accept or start dealing with bitcoin. As the quote in the op said, oil is traded in dollars and it's why America goes to war over oil because not trading in dollars would be devastating to their economy and geo power. In fact, I read that one of the reasons Libya was invaded and Gadaffi ousted was because he was going to start trading oil in his own gold-backed pan African currency he was going to create (though maybe that was just a conspiracy theory but it wouldn't surprise me at all if it was true).
