as they use a bit of a wobble in the picture as the measure for detecting anything that far, i dont really see how they can be more specific that "there's an object". its not like they can discern shapes or anything.

And only 1500 light years away. What we are seeing now occurred in 515 AD

Yes, damn you the speed of light. However, the mere presence of an alien structure, Dyson Sphere or not would be a game changer for the evolved apes on THIS planet.

Also, and civilisation that was able to construct a Dyson Sphere 1500 years ago could be far advanced by now.... Or extinct

...OR on their way here.

You sound like you know far more about this than makes me feel comfortable. What is your dastardly plot, I wonder? I have a twitch in my sonic skrewdriver finger . . . .

I remember Larry Niven's Ringworld books. They featured a Dyson sphere. Amazing concept and unimaginable to me that one would be discovered in my lifetime.

What? Have you actually read the reports?

http://kepler.nasa.gov/

Kepler doesn't measure wobble. It measures starlight and looks for the characteristic dip as objects transit the face of the star between it and the spacecraft. It relies on line of sight and so only works if the plane of the orbit is in exact alignment. This implies then that it can only discover a fraction of the stars with planets. What it does mean is you can deduce the size of the object. Something reduces the starlight by 22% (as seen from Earth 1500 light years away) of a star 1.5x the size of our Sun must be vast.
