[AGENT++] Access to Management Information

each device can have its own mechanism. For agent++ the best access
mechanism would be a C++ API, where you can call get_value_xxx() and
register a callback function for changes in the device. Some devices
will possibly come with a program that uses some proprietary method to
get the status information, so the agent++ agent would have to call this
program and parse the output.
