The initial goal of XAT was to deploy several displays (not in the means 
of monitors but how Xorg abstracts this) per X server. This could be 
used for instance to deploy a multiseat system. We decide to frozen the 
project given that Xorg community thinks that is more sane to start 
several instances of Xorg.

However if you want to start several instances of Xorg in todays 
upstream branch you will face some problems due to VGA legacy interface. 
Some video cards know how to deal with this and some not. So we are 
developing some scheme [0] to fix this all.
