I find that works better for my usage, because a given host on my Smart-UPS 5000 might be down at any given moment for testing, and if its the one with the single usb connection, I'm out of luck. Instead, I have apcupsd on each host talking to the UPS's onboard NIC and running independently, with the ability to power off the UPS disabled (by using the read-only SNMP community).
