With Net::SNMP main concern is reading data from some server in the network.

The question is - how can I export that data, so that someone using for example Net::SNMP is able to read it?

In other words - I need to be able to act as a SNMP server, but since you normally already have SNMP agent running (be it Windows Agent or unixish snmpd daemon), ones needs a way of exporting some variable via that previously-running daemon.

To do that, you need some way of plugging into that daemon..., I hope I cleared it up.
