Here are some stats about the change impact on our test database. I've 
used the following definitions:
- an identified device is a device with TYPE, MANUFACTURER and MODEL 
elements after discovery
- a supported device is a device with SNMPMODEL element after discovery 
(recognized could be a better term)

Basically, this feature allows to identify 90% of network devices, and 
some printer devices too. The identification failure result either of 
missing values (alcatel devices), which is a solvable issue, or lack of 
discrimination of sysobjectid for some printer manufacturers (HP), which 
is a limitation for this approach.
