Have you take a look at https://en.wikipedia.org/wiki/Rainbows_End_(novel) ? Dr Vinge does "thought bombs" a lot with most of his books where you read something and he has all kinds of implications that jump out with one of his concepts.
But all of them tend to have something - "Reality Graphics" in A Fire Upon the Deep, the localizer net and the Focused in A Deepness, Rainbows End above considers why you might have an underground market in Bootleg processors... Interesting stuff to ponder.
