I haven't tried rendering to VBO before but it's my understanding that the technique used to render to FBO, then copy the appropriate buffer to PBO, then re-assign this PBO as a VBO. You might be able to implement this right now using a post draw callback attached to an osg::Camera set up as at RTT to FRAME_BUFFER_OBJECT.
