Is this that thing about the space hotel, or whatever? It's definately an advancement. It would have to be horribly expensive.
In the next 100 to 50 years, it would be as cheep as airplanes are now, and as common as they are, too. If all goes well, that is. It's definately a step forward, and if we make that step turn into a walk, we'll eventually be able to run.
