A company claiming to be interested in buying Viaweb instead copied us (as well as they could) and went on to be very successful. They didn't kill us, because they were in Japan. But I expect they did make it harder for Yahoo to launch a Japanese version of Store.
It was so early that we had no books to open, and they were business guys who would not have understood our code if we'd shown it to them. All we did was explain what we were doing.
