You make a good point, Jack.
My similar inquiries to MC have so far been left unanswered as well. This makes me assume that their infrastructure (solid as it is) still relies on the existence of their entry point servers even if they like to give a different impression. So far I have seen no info about how reconnecting to the network would work without their servers. Nor is there any experience on how solid and vital the network would remain if MC's server farm would go down. If I would have to guess, I would guess that the network is yet far from being 'on its own'.
