Yes. Although it would be possible to add the lookup (forward and  
reverse) functions like in usbhid-ups (which would allow for better  
conversion between IOD <-> NUT values), it would be much better to  
start from scratch here.

Yes and no. It indeed does talk SNMP, but as far as I can see doesn't  
support changing variables. The only method for changing the  
'battery.runtime.low' parameter, is through the HTTP interface. I've  
not been able to change a single variable through the SNMP interface.

Currently it reports

     Network Management Card V6.00 HB (SNMP)
     Network Management Card/Mosaic 4M 16M/HB (XML)

This is the latest firmware I could find for the NMC 66102 (technical  
level 09).

It would probably be easier to have access to a device with native  
SNMP support. I don't need physical access to it, it's enough if I can  
reach it through the net.
