I agree with Hal; I think it's easy to find an optimal moral code once you make some basic decisions as to what you regard as a good outcome, but you can't say that one moral system is objectively better than another because you have to make those initial subjective decisions.
For example, I think that taking a short-term loss to make a long-term gain is better than taking a short-term gain for a long-term loss, which is one reason why I think that libertarianism and anarcho-capitalism are much better than authoritarian systems; limited government can't stop people starving in the streets, but it can't lock you all up in concentration camps either. But that doesn't mean that I'd be able to prove that they're objectively better than socialism, unless the others also agree with my underlying subjective choices.
Now, you can probably come up with a set of rational, subjective, transhuman axioms which most of us would agree with and work out an optimal moral system from that; but it still wouldn't be an *objectively* optimal system because others have different axioms. They might be irrational, but irrationality is their choice.
