This is quite interesting idea. Especially if you're willing to provide 
the code directly :P

The first point is to determine how to extract UPS informations. In 
fusioninventory, they are currently two different ways for this:
- local devices are managed in local inventory task, using whatever 
command/tool available
- remote devices (thoses with an IP adress, basically) are managed in 
net inventory task, using only SNMP currently

Some kind of devices, such as printers, can belong to both categories: 
small ones are locally controlled on a specific host, while larger ones 
are autonomous. I guess UPS are quite similar in this regard, some of 
them being attached by an USB link to a controller host, others having 
their own network device, right ?

In this case, UPS support would mean two additional pieces of code.

Local inventory support is just a matter of adding a new additional 
inventory module, in perl, for the local inventory task. There is also a 
new section definition to add to the inventory data structure, but 
that's trivial to do.

Remote inventory support is a bit more complex. First, we need an SNMP 
description model (just a mapping of OIDs against specific known 
properties), but as currently this task only manage printers and network 
devices, we also need to define those properties, and add explicit 
support in the task code itself.

So, the easiest way to start would be the local support. Have a look at 
the generic local printer module, in the 2.2.x branch, it should give 
you some idea on how to proceed:

Of course, feel free to ask if I'm not clear enough.

That's easy to fix, but I can't be bothered.
