At a 2600 conference long ago, we built a cluster of public X11 dumb terminals, so hackers at the conference could browse the web and such. We hardened the server against local user attack, and the clients booted from a read only solid state media (aka, floppy disk) with no port access. But how do you harden a physical network against a thousand hackers? Solution: token ring. We made the network so ancient that nobody would have the hardware to hack it that weekend. Worked great.
