For that matter, when people start doing 3D desktops, everything will

the right time anyhow.
Would it be possible and beneficial to make a such buffer-system for 2D
and in that way get around problems that may occure on tv-out?
It would be possible, but it would require that the X server keep
track of the contents of every window. I believe this is something
being put into the DAMAGE extension, so in that case, it is possible.
I'm not sure about whether or not it would help with the TV. I
suppose both fields were rasterized and then you switched, that would
work out well.
X is going to a full OpenGL based rendering.
the one important thing is pinnable buffers (each windows needs an RGBA
buffer - texture or something) so that it could be drawn on independently
then each window is composited onto the main frame buffer
