>"Export formats: PDF, SVG, pixmap, BOM, pick&place, Gerber/Excellon". None of which have enough info for import into another EDA program. This thing is very self-contained, which is unusual for an open source program.

The limitation here is that only KiCad has an open format for design files to begin with. Maybe we should be agitating for a better open-standard for schematic capture? I'd love to be able to output a schematic from e.g. a spice simulation, then import that into my ECAD suite. The netlist (which is part of the Gerber output) is human-readable, so I suppose its possible to extract the schematic from that. But then, it'll be computationally expensive to arrange that information in an easy-to-read format.
