OK, as long as you are aware of the race condition inherent in utilizing
the information on whether the component is active, I'll try to explain
how I would do it:

	list = oaf_query("is_rodrigos_component = true");
	active_list = oaf_query("is_rodrigos_component = true and _active = true");
And then use active_list to go through the list and mark things as active.

Right now, I don't think the OAF_ServerInfo returned from oafd includes
the _active field in its list of attributes. Whether or not calculated
fields like that should be included is up for debate.
