Sattelites can only multicast as they are to expensive for unicast
(calculate costs per bandwith)! I don't think T-DSL by Sat will have a

Internet by sattelite's only future is bankruptcy.

But what about a solar-based WLAN-net in settlements?
I mean a WLan-Router every 500 meters with a solar panel ... :o)
