This morning I had been testing the scalability of the Blender/CORBA Event Service connection thingy. Unfortunately, it didn't look good. I started to investigate the possible problems and changed the IDL to have lower overhead and better scalability.
Now, I have been playing around with about a dozen Blender objects moving around and rotating according to the coordinates specified by a CORBA server feeding events. So, it seems to work now. There still are some issues though.
I rendered this silly Blender-CORBA animation to a video.
