I dig this old topic, but we from the KICAD EDA project were still looking for new developers and testers. KiCad is a GPL kit for drawing circuits, printed circuit boards and viewing gerberas. It is written in C ++ using the wxWidgets toolkit and can work on the basis of Windows, Linux / BSD and Mac OSX.
Learn more about the project at: http://www.kicad-eda.org
And the project is now placed on the launch bar.
