You've been able to do this for a while now, if you had multiple graphics cards. I have never thought about using multiple outputs from the same card, though. I can't see why it shouldn't be do-able with a little work. The last time I looked into something like this (which was for an extension activity for my NatDip students), it would have been easiest is you used multiple PCI graphics cards from the same vendor (but they'd have different PCI device numbers, so could be identified separately) and using USB keyboards and mice (for the same reason - unique identifiers). That way you could tie in specific keyboard/mouse/gfx cards together and run multiple X sessions at once. I might have another look at it again. Cheers.
