[ILUG] hardware ID

[Vincent Cunniffe]

While thinking about the subject of secure consoles, etc., I thought
of hardware ID codes : is anyone familiar with any schemes whereby 
a keyboard or other peripheral has a unique code which it communicates
to a server, and without which the server will not accept input?

Sort of like a pre-smartcard security technology.

I've never seen or heard of this, I was just wondering if it existed
in any shape or form.
