IIRC, something like that actually happened. Except it was a file server that threw your whole directory tree up on the net. oops! Why you ask? How could that even happen? It was just a few years before everyone had Internet, so it was assumed that your network was a LAN. (Source: http://www.grc.com/su-bondage.htm)

Of course, everyone should have really had a firewall anyway, so this was obviously cool right? After all, it's up to the user to secure their machine.

(Disclosure: That was sarcasm.)
