I think the main motivation was more the fileformat itself, as it
certainly seems to be gaining popularity. McNeel & Co. definitely did
a good job with releasing the openNURBS toolkit as opensource.

I have no personal experience, but I think it's pretty good actually.
Maybe Josef Grunig has some input, I know they've used Rhino to some
extent.

A rendermesh is just a "renderable" representation of a Brep face,
e.g. a tessellation produced by Rhino and stored in the .3dm file
along with the parametric patch. Supporting it would be almost
trivial, but didn't have time to add that. Maybe tonight (if I don't
get wasted in some biergarten on account of the nice weather :-).
I think basically all types of geometries should be supported, there
are some shortcomings though (e.g. no texture coordinates). I don't
think Rhino supports subdivision surface modeling, but there exists a
T-Spline plugin which claims to be able to import subdiv surfaces (in
polygon form) into Rhino.
Yours,
Ákos
