I find that way too many people don't have any concept of what a mainframe is and mainframes are still around and still being used behind the scenes. Most supermarkets and pharmacies work from mainframes and sometimes the people who use them are idiotic. I have seen someone who messed up an input screen turn her terminal off then back on and she was totally surprised when it didn't reboot but came back on and showed the exact same messed up screen. When I use a terminal emulator and choose VT100 I feel cheated because my school had VT100s and VT52s. The VT100 was the best terminal ever made, in my opinion and an emulator just makes me nostalgic.

I have seen a demo of this tech. It really is fast and easy to use and go through. You just walk through it, wearing everything. The only caveat that I saw was that people had to be separated by about 6-8 feet as they walked through to let the scanner work properly.

You can sometimes guess the really old AOL email addresses from the way they leave out vowels or use shortcuts. The original AOL email addresses were limited to 10 characters. I have several email addresses that I use for different things but I will never, ever give up my ancient AOL address. :-)
