My understanding of Gate/Lane tech is that the only reason Ageria can build it is that the DK left behind designs of the stuff.
That's to say, nobody ever researched 'how to do it'. Liberty was handed a technology beyond their understanding in pictures.
That implies that, perhaps, the parts can be looked at and replaced...tada, mass production.
Of course, the way I want to understand it is that liberty was given a way to make a factory for a thing.
And a different thing
and a different thing...
And, as such, looking at the objects wouldn't help reverse engineer them, because the objects themselves don't have to make any damn sense to anyone on the very edges of human science today.
This gives Ageria a better reason to keep them secret than worry about competition, a decent patent law agreement among the houses could do much better, if you could publish the information without, say, breaching the national security curtain around the fact that there's an alien arch teaching Ageria things..
And, to point out, it makes not much sense for there to be laws against subverting the technology and Ageria to go to a great amount of trouble trying to keep it a trade secret. Laws as such are designed to replace trade secrets...
Anyhow, nobody asked me how the lore was to be written. (which is why it's silly)
