Import/Export Rhino's 3DM format to/from blender Is there a plugin to import/export rhinoceros' 3DM files to/from blender?

If there's no plugin yet, would it be possible to write one or are there technical limitations to do such a thing? I suppose somebody would have written something by now...

I'm asking this because I swap files with people who only work with rhinoceros, but most of them only know basic modelling and panic when I start speking about STL file-format.

Thanks in advance
I have successfully imported a 3dm file into Blender on manjaro linux using following plugin : https://github.com/jesterKing/import_3dm
