Europe's New ET Life Search Programme

hotsauce writes "The Guardian has a report on Europe's ambitious new programme to search for extra terrestial life. ESA has started a program called Cosmic Visions which will launch a series of satelites, starting with Gaia in 2011, and possibly culminating with the Exo-Earth Imager, a mission consisting of 10.000 3-metre mirror telescopes. The French are leading the charge with Corot in 2008."

    We have all these programs for trying to find patterns in signals from space but are we doing anything to make life easier for anyone that is trying to find us? Sure, we are emitting a bunch of electromagnetic radiation from our broadcasts but how far would it actually reach to be detectable? Wouldn't it be more efficient to send powerful laser pulses that are specifically targeted at "promising" nearby star systems?
    Is anybody in the world doing something like this?
