DXF doesn't support CSR but it does support projected coordinates.

Christophe > With QGIS 1.7 and gdal 1.8.0, you can save as dxf a .shp in 
Lambert 1. WHen you open the resulting file in Autocad Map or DrafSight, 
you can see that the coordinates used are the same.

If you want to work with several CRS you'll just have to make the extra 
step of setting the correct CRS in Autocad Map and save as dwg.
