I'm not sure how easy it would be to communicate, and insulate from marketeering. "Steel roll cage" or "Airbags" and "Seatbelts" are relatively simple concepts.

I don't know that even something as common as "SSH" would mean much to the average person, and by the time they learned, any given term or technique would probably have been supplanted by another, newer, better one.
