Most newer switches can lock down how many mac addresses are allowed to be sourced on one port.. if that amount is reached, the port can be disabled or other action taken (snmp trap, etc)... I know there are plenty of cisco switches that do this anyhow, I'm sure there are others...

I guess you're actually aware, that not everyone is locking up rooms containing switches. And just plugging out unused cables won't be sufficient, since usually I just can plug out any computer and plug in my own.
