Frank, can you do a very rough estimate how much it would cost to implement the read/write dxf driver based on your proposal? Would you deal with dwgs also, or just dxf - how similar/different are dxf and dwg?
We could help financing it, but not the whole thing. If a couple of interested parties would collaborate for the financing it could work. dxf would definitely be interesting to have in ogr. I know that there can be a wide variety of dxf files from the different products that generate dxf.
