Is Fluther renting space [or some arrangement] on its servers for Q and A sections of new partner sites and is Fluther providing the engine for those sites' Q and A?

I’ve heard mention of “Federated Fluther” and that FF Qs are labeled as such. I have never seen one. Will they get their own category? How does it work? Are [say] Sierra Club’s Qs asked on their site but also post here and our answers post there? Do only beta testers see their Qs? How exactly is a Fluther partner a partner?
