Yup. I think exporting PCB files to other formats is pretty easy (anyone want to write a DXF exporter for the new HID system? ;) but finding something to *do* with those formats is harder under *nix. OTOH, a pcb to quake converter would be interesting. I often render woodworking designs as quake maps so I can walk around them and view them in various settings. I think the tricky part would be getting the mask and silk layers to form against the copper/fr4, rather than being a flat sheet just above it. Another option is a GUI HID that uses OpenGL to render the board. It would be OK to be view-only, but it would be cool to still have the show/hide layer, zoom, and mark features.
