	If you think physics, you think atoms. But software authors
are not dealing with atoms. As rms says, if you give away a piece of
bread, you no longer have it. If you give away a piece of software,
you still can have (and use, a give away) your own copy... Users or
programmers are not pressed by any "physical" problem when they give
away software, as they are when they give away atoms.

	But per copy charges are only possible because this kind of
"giving away" can be forbidden, and that forbidding is enforced by
(current) law. That's what I meant by "non natural".

	BTW, when you are charging per copy, you are not linking
your revenues to the value that your product generates for your
customers. You are linking your revenues to how many copies you manage 
to sell. If we were able of measuring the added value that a software
product generates to its users, that could be a reasonable link for
revenues, I guess... However, this is already too much off-topic...

	Right. Or you can look it the other way around. Because of
the viral attitude of software patents and RSA's licensing...


PS: Anyway, I'm not proposing any particular way of earning profits as 
"the only one and the rest is evil". I'm just trying to find new
