I've been looking into another apc upsd.
http://www.brisse.dk/site/apcupsd/

This one seems to be a bit more advanced than the FreeBSD upsd. Its
supposed to handle all the APC UPSs. It even has support for a network
side for the UPSs. This way any box connected to the UPS can talk to a
master which is connected via the serial cable to the UPS.

I haven't tried it under NetBSD yet.
