My read on the situation is that you copied OCP only inasmuch as OCP made some observations about physics and you made the same observations.

The most obvious change is that you guys use half-width, full length enclosures.

But I'm realizing now that I haven't looked at the OCP specs in a long, long time. I recall the common DC rail from some early Facebook papers on this topic, and I thought they were pretty similar to how you plug into power.

I just looked at the OCP power connector, and I would have lost any bet anyone was willing to make me about what they looked like. That's not at all where I thought we were. I think I understand now why you guys went to such pains getting the keyed connectors to work exactly right. Their power connectors look like something from a scifi movie, and not in a good way.
