It's somewhat of a technical problem. It could be done with indirect rendering (opengl commands are send through the X server via glx), but that is not yet hw accelerated. right now id does work with sw rendering. With direct rendering the 3d app talks directly to the hardware via libGL, bypassing the Xserver. if you wanted to support direct rendering with xinerama you'd have to have some sort of intellegent dispatch layer to coordinate rendering between potential multiple 3d engines. Once we have hw accelerated indirect rendering, we could disable direct rendering when xinerama is active and use glxproxy to dispatch 3d commands to the backend X servers. Mergedfb works because it's just one big framebuffer with two viewports looking into it so the 3d engine treats it as such. It provides it's own version of xinerama so apps know how behave from a screen persective.
