My understanding is that all mechanical LSDs work this way, (gear, clutch or otherwise).

Now, you are correct, a loss is a loss.
And again, you are correct in saying that even hardware LSDs are not 100% efficient.

I guess another good analogy would be that this system *would* be more efficient if the disc from the brakes on the spinning wheel were attached to the opposite wheel somehow (lets call it magic).
In this case, the exchange of energy would be such that even if the brakes were to grab the disc solid, the wheels on both sides would then spin at the same speed. The spinning wheel would pull the other wheel to spin faster by both the action of the diff under braking AND by the action of the disc itself.

Not sure if you see what I'm getting at.

Man, this is so much more fun than trying to figure out why these stupid digital controls are not receiving my data packets correctly... yeah I'm at work.
