Another option to look at is to include DXF in the base program, and then have DWG available via a more limited distribution plug-in. There are several GPL softwares that function in this way when dealing with a 'closed' part, like the mp3 libs with certain player/encoders. This way the base program could be included within larger linux distributions, but the add-ons that might be crippled with more stringent licensing would be available for download for those that needed/wanted them.
