Yeah situations I've described. I didn't really give much background information. IE: I was having a conversation with some techie friends back when the SOPA scare was still at its peak. We were discussing purely hypothetical doomsday scenarios that would involve a "darknet" and the technical implications of creating an entirely subversive network. The idea was brought up that we could use our existing telephone infrastructure to send data, and only a way to transfer data via sound would need to be developed. This was shared amongst a few of the participants until I piped up and said "you know dialup has done this already, right? The information is already there." This is a conversation amongst people who are involved with and passionate about technology and are around my age or older. These are the kinds of people that I'd expect, if not to think of specifics right away, but to at least be lead to something that was as pervasive as dialup. True, I don't expect an 18y/o of today to know or think about it, or even a 20y/o, but a 25+ hacker, developer, or general tech geek? I'm just surprised at how many in that former category just don't remember it.
