[Baron Munchausen]

Isn't this realistic? How do most technologies spread? Someone gets a sample and figures out how to do it for themselves. I think the age of 'intellectual property' has distorted people's view of history. Copying has been the rule, not the odd exception, and has not been regarded as 'immoral' or 'unfair' either. That's a recent thing introduced by obsession with squeezing the Last penny out of patents.
