per-window backbuffers and a bunch of other stuff. Actually, given enough memory, each time a swap happened the driver could just allocate a new backbuffer to render to. When the swap happened the old backbuffer would be freed. Nevermind that tangent for now... ;)
Do you ever need more than two back buffers. If back buffer 2 is filled and back buffer 1 has not been swapped to the front buffer yet, then back buffer 1 is obsoleted by back buffer 2 and can be reused.
Not for a game, but for animations or other things you might. You are right, though. Two backbuffers (triplebuffering) is probably always enough.
