Build in an airport-connection ALARM into the router – when a computer is moved or closed (loses its IP), the alarm goes off.
Works via MAC-address recognition.
A background app running, (which stays open upon quit), and signing out with the right code dismantles the alarm for this computer.
Signing on to the router would be automatic – correct MAC-address connects the alarm
Computers unknown to the router get no alarms.
IDEAL for systems with always-on policy, eg. notebooks in a home, servers etc.
