I handle this by having the machine that is physically attatched to the
UPS and monitoring it with apcmon send its syslog output (for local6)
to the other machines that rely on that UPS.  These machines run
apcwatch which is a similar script, but just gets its info from syslog.
You then configure the "watchers" to shutdown sometime before the 
monitor host.  A bit tricky here because one of my watchers is the 
NFS server that the monitor host relies on :-)  I really need
a multi-port com card :-)
