You still have to worry about bandwidth, eventually you are going back to a landline--not like sat. beams directly to every site on the internet.
It's the same as DSL, they claim you don't share bandwidth with your neighbor, but, eventually you all get stuck on the same pipe.
And, Sat has very high latency. It takes time for the signal to reach orbit and back, even at the speed of light.
Visit DSL Reports, they have forums for just this topic.
