Right--as I understand it, it's not that different than Google's "Meeting Room Hardware Virus":
"I imagine it started with all of the adapters which were thrown around in every meeting room. Everyone with a Macbook of some flavor needed a DVI to VGA adaptor in order to use the projectors, so they were plentiful. Somehow, someone probably damaged one of them and smooshed a couple of pins into places where they should not have gone.
"Then, someone else forced this into their Mac. Perhaps two pins tried to go into just the one socket. At any rate, it would now break the socket and get it all out of whack. That socket, used with another adapter in another room, would then break that adapter. This new broken adapter would then go on to break even more Macbook DVI connectors.
Thus, we had a hardware virus." [1]
