Does it really play ball in the context of metaethics?

I'll define morality and ethics as a normative system (operating on different levels of abstraction, with different targets as their focus, but maintaining the same kind of interaction) emergent from imperfect information transmission between any two points in space-time, i.e. the same body at t=n, t=m; or two different bodies at the same time (just to account for quantum stuff) which occur at level of complex life. I'll say life is any system with the capacity to maintain or decrease entropy (Schrödinger is where I first saw this) for some period of time, and intelligent life meets some threshold for delay or non-direct determinants of information from outside the continuous body to manipulate its environment to a lower entropy state, one which does not as of yet have the same quality of decreasing or maintaining entropy as the intelligent lifeform does.

In this case, metaethics is a distinction in the realm of a type of interactions yet still a part of them. It's like one pizza, you can cut it in half and say you have a left half and right each belonging to the meta and non-meta partitions. Or you can say that what we regularly refer to as morals or ethics is simply the toppings, metaethics is the dough which is frankly too frequently ignored in discussions of ethics and pizza-quality. The dough similarly provides the framework or support for the toppings, without which you would have a spread out cheesy and saucy salad (if veggies are a topping, otherwise you have what I make in the middle of the night when I don't want the microwave to sound off to warm up food that would fill me up) which couldn't be characterized as pizza.

Sorry I think I changed topic there, I hope some of the point comes across.
