[Feature request] Multiple X servers on one graphics card?

[Tomasz Borowik]

I wonder if a custom window manager wouldn't be enough? Using
multi-pointer and locking each focus group to a given screen, making
sure that no one can interfere with anyone else. If the wm is root it
should be capable of spawning programs of different user privileges on
each screen. Of course that is far less insulated and in effect
probably less secure, but it should be easy to do and might be much
more stable, also it should work on whatever hardware you give it.
