As interesting as it is to infer the existance of gas giants by the wobble of their parent stars, I hesitate to call this a home away from home since nothing can be inferred about any terrestrial planets that may exist in orbit. To my knowledge (which is admittedly lacking in some areas) we have only observed one planet directly, when it passed in front of its star relative to our position. The rest we see by measuring the osillations of a star and we can only measure the largest planets this way. Nothing is yet known about small terrestrial worlds like ours. Our small world wouldn't add a wobble that we could now measure from lightyears away, but we could infer Jupiter's and Saturn's pull. I think what this article boils down to is since this system has a gas giant in the middle, there might be rocky plantes closer in. Since we don't have a moonbase yet I'm nonplussed.

NASA scientists, starry-eyed dreamers that they are, are building a spaceborne telescope to spot earthlike planets. Launch in about 4 years. Another eartlike planet spotting telescope to follow a couple years later. And another. It won't be long, unless, of course, they don't find something.
