So the US government and Vint Cerf want to take the Internet in to space. Gee whiz. What a tremendous waste of money. 
Why, exactly, do we need an inter-planetary Internet again? I'm guessing that there are a whole load of Jupiterians out there who want to put their camera phone videos up on YouTube.
The idea that this is a military project is pretty ridiculous too. You know what would help the "boys and girls" (read: hired killers) in Iraq would be little things like body armour, not TCP/IP powered satellites.
The actual use case of "Internet in space" has not been properly fleshed out. I'm kidding about the YouTube thing (as you may have gathered), but what is the point of this?
