APC supports remotedown. Basically you can configure a computer to shutdown if it
stops sensing the other computer is up. A computer is designated as MASTER and the
other as SLAVE. The SLAVE may be configured to shut down if MASTER disappears. The
danger is that MASTER could go down for reasons not related to power outages. SLAVE
may also be configured to recive signals from MASTER, which is a bit dangerous in
itself.

A dangerous approach can be seen here too:

IMO best approach for a home lab is an UPS per system, each with a comm link to its
respective computer.
