Yes, they stopped many plugins but have a Stand-alone Arion with OBJ import for the likes of C4D, Sketchup, etc..
They have Rhino Live, Max Live and soon XSI Live which are more tightly integrated in those packages.
Much progress. Whatch their blog at: http://randomcontrol.com/blog/
Yes, they have no community forum now, so I would like to see one here please.
