Yes, but it was a bit confusing. You said:

Over in this thread (last couple posts), it appears that it's possible to make NUT on the ReadyNAS to talk with the card directly, but I don't have the knowledge of how to go about adding this capability.

Whilst you mention that a different thread has suggested that direct communication might be possible, you don't indicate that indirect communication isn't acceptable to you.

Anyway, now to your latest statement:

However, I presume if you can put a service on a Linux box that reads from the card directly, we can do the same on the ReadyNAS...however, I'm not sure how to install and configure it. Perhaps might we install the server and then configure the client on the NAS to look internally? Ideas?

Well, first of all you have to install a development environment and compile the NUT server from scratch for the ReadyNAS's ARM processor. You must take care to include the snmp-ups driver, because that's required to query the APC. Next, install the software, preferably as a proper ReadyNAS package, and configure upsd to query your APC and run on 127.0.0.1. Finally, make the NUT client query 127.0.0.1 as if it were a remote ReadyNAS.

There's quite a bit of work involved in this method and that work will get blown away every time you install a new version of the firmware. I decided it was easier to run the NUT server on a local Linux server and have that monitor the APC instead.
