Hi Oliver, thanks for trying it!

I forgot to mention, but  you probably figured it out, that the patch should
be applied from your blender ndof root folder.

Correct.

No answer is great! Means everything is ok. :-)

Make sure that in source/blender/src/ghostwinlay.c::window_open_ndof()
you specify the correct path to the plugin. (I have to use the absolute
path, relative doesn't work for me.)
The plugin is loaded by blender with a dlopen() function call (man dlopen
for more info), you can't run it by itself.
If the 3Dconnexion driver is not running, the plugin should abort its
initialization routine and do nothing.

Yes it certainly was. Feel free to let us know any problems you see with the
code and make corrections/suggestions if the implementation doesn't work as
you expected.
