I'll be curious to see the results, but I think sometimes predictable
and stupid may be the best route with these sorts of things. In
particular, I'd worry that a content-independent measure of entropy
might miss some subtleties of a particular language (e.g., that "*" is
more or less meaningful than some other character). But we'll see. :)
