And this is why geeks make bad lawyers. "Surely," they say, "if A is allowed, and if by a set of trivial extensions we can turn A into B, then B must also be allowed". But the law looks at A and B and sees two very different things, draws a hard boundary which might not make any particular sense, and doesn't care about careful analytic arguments. Here's another copyright problem. If I have a party and screen a DVD to ten people, that's fine. If I have a party and screen a DVD to twenty people, that's fine. But if I have a party and screen a DVD to five hundred people, I'm holding a public screening and it's not allowed under the terms of my DVD license. How can this be? It just is.
