Some of it was, yah. I don't claim that any of this is original. The
problem with SET was that the protocol was far too complicated to
implement (hell, the spec was nearly too heavy to lift), and it was
proposed well before people even had USB connectors on their
computers, let alone cheap USB card interfaces. I think people threw
out the baby with the bathwater, though. The general idea was correct.
