Cable and DSL also have an 'outdoors' component, adding an external antenna for either improved bandwidth or to get the thing to work at all should be an option for a new broadband medium.
And when you're on the move that doesn't matter. One way to make it work untethered indoors is to simply bridge the satellite downlink box to a wifi repeater. That would get you coverage indoors and outdoors from regular devices around your house, and if they sell enough of these downlink boxes they could conceivably pool the bandwidth by creating a mesh of them.
All kinds of interesting options, even if it doesn't work directly indoors.
