Autodesk, DXF, OSGEO

I note the same Autodesk funding OSGEO is also the creator of .DXF,
which one must jump thru HOOPS and turn purple even thinking of
converting to other formats here
on GNU/Linux.

And also they created MapGuide, which is the main impediment to me
being able to use
http://basicmap.moi.gov.tw/
http://gis2.tccg.gov.tw/
http://doorplate.taichung.gov.tw/

I even went to the public library to use Windows(tm),
but "no administrator privleges to install" MapGuide.

I doubt http://mapguide.osgeo.org/ can help.
