No argument at all with regard to human language.

Do you mean digital documents and information in general, or actual binaries?
What I'm getting at is that with compilation and the optimization
voodoo performed by the tool chain tends to heavily modify an
information. Add to that the that the "interesting" code may only be a
small portion of to whole amount and the fact that it might be further
obfuscated it doesn't seem realistic to me that there would be enough
unique info to do this in any reliable sense.

Yeah, but it'dbe a nightmare issuing subpoenas for the guy who made a
virus kit and the ten gazillion little jerks that used it.
