Haha. But DNA is a very good example of what I'm talking about. It's both "code" and "data" at the same time - or rather, a perfect demonstration that these concepts don't exist in nature.
So for you to successfully use my DNA as code, without also borrowing the compiler from my body, would be a major scientific result, shining light on the questions outlined above.
So in short: I'm happy to contribute my DNA if you cite me as co-author on the resulting paper :P.
