You probably refer to direct rendering (banging on the graphics iron directly) and indirect rendering (transmitting all graphics primitives via sockets), using the GL over X protocol (=GLX the protocol). The latter has been realized with the Utah glx module for 3.3.x servers - but it is slow due to protocol overhead and of course because the driver does not use low level features of the nvidia chips, like DMA.
