So, it seems that the manner in which the message is delivered is extremely important. Most people I know get the "deer in the headlights" look if I try to explain it in the usual computer gargon. However, a well thought out metaphor like yours can work like a charm. Now there's one convert of sorts; Maybe he will explain it to someone else someday... and no I don't mean "he will tell 10 friends and they will tell 10 friends..." It is a "VERY SLOW" process and one that may never develop sufficient momentum.

Lastly, I admit that my view is probably slightly askew as most of the people I am around day to day are not technophobes but they are not techies either. Just intelligent people who know the world is not black and white.
