For what it's worth, the WCCC's Rule 2 seems to be a lot like a university honor code (if you do borrow code or ideas, make sure you cite it.) I don't believe that's too hard to follow. Maybe someone should fund a kaggle competition to design the best chess-playing program, with the final requirement of making the code open-source after :)

Given that most of what you'd implement a computer chess engine is pretty much available online (at most,behind a paywall), and digging through the source code of GNUChess and Crafty would give a lot of insight into the scoring function, so, yes, the score function would be pretty much similar in most parts unless someone comes up with a radically new way of doing things.
