I've been doing boards with smooth arcs at the turns and 6 mil trace widths and .01 mil resolution allows making accurate footrpints for 0.5mm lead pitch parts. All using pcb, and driven by the gsch2pcb program that updates your layout by creating a "diff" layout of unplaced, (stacked on eachother), parts as a result of schematic changes. One can take that "diff" layout, arrange parts, copy to a buffer, load the last version of the board, paste the new parts in the margins, load the new netlist, and rework the board to match changes. There is also a program called gattrib for editing schematics to add resistor values, change package sizes in lists spreadsheet style. gEDA is becoming "handy".
