Needs 1 and 2. 5. Needs 2 and 3. Getting statistics out of the database. This can be a few objects running under a Corba architecture. However, this will make installation more difficult.
Daemons are easy to setup.
As long as there isn't a standard ORB installation on any Unix, I'm not sure if this is ok. If we also have Eiffel Corba objects, it can serve as a reference how to do this to others. Maybe an Eiffel webserver to get the basic statistics, or just use Small-fcgi and use apache. Building your own simple webserver is easier for setup. And maybe a simple client query tool text or GUI based.
