Have we settled on a date in the timeline when this became widely available, or available to the military, or anything like that?

Not a firm date. As with all this kind of stuff, as we take the first pass, we put a couple of pins in, but we don't pin everything down until we really need to, because if we make it too rigid, then when someone comes in and says, we think for gameplay we need to do this, then we have a lot more work fitting it in. But if we just have these broader strokes of what we know, in 2949 the tech was there and by 2951 it was widely available, we can massage everything in between as needed.
