The server should track how recently it has been contacted by all the clients it knows about.
It should display that information in a color-coded list view (e.g., green if contacted within 1 time period, yellow if it missed one, red if it missed 2).
The server should send an alert if a client goes red or it receives any other error from a client (implies a cron job periodically checking the list).
There needs to be a way to remove obsolete clients.
