So the mechanics are somewhat supported directly by bitcoin, but, how does the bitcoin customer get their money back even if the escrow company agrees that the terms of the sale weren't met? (added [1]) And then you still have a question of whether the parties agree to a mutually trusted escrow service to actually administer the signoff. I imagine that credit cards are somewhat partnered closer to the customer/card holder, but with bitcoin escrow it could be either the vendor or the customer? Not meaning to criticise here, just a walking through unfamiliar territory.
