Doesn't this result in some objects getting sent to OpenGL twice even though they will get clipped by the near/far planes? For performance and ease of high level management I would still strongly recommend the slave Camera approach. This approach will allow the view frustum to cull subgraphs efficiently so that only components that will continue to each partition will be dispatched to OpenGL.
