Internets In Space!!!

A programme to kick-start the use of internet communications in space has been announced by the US government.
The Department of Defense's Iris project will put an internet router in space by the start of 2009.

Even more sci-fi is this:

"With IP becoming more prevalent for use in space, Nasa and internet pioneer Vint Cerf have also investigated the possibility of using internet technology across the solar system. Although some work has been carried out on the necessary standards and protocols, no definite schedule has been announced for this interplanetary internet. "
