   You are talking about the linuxconsole project. Yes with alot of work
we got a multi-desktop system working. We even got several X servers with
several patches running on different desktops even tho they where working
out of one box. The main problem with this research was the console system
level of code was intertwine in each input and display driver. In 2.5.X
you see the moving of the console keyboards etc to the input api which can
function indepenedent of the console layer. You also had the same effect
with the new framebuffer layer. This was done to make driver writing easy
and to help the embedded space as well as prepare for the future
multi-desktop of linux.
   What has not been done is true multi-desktop support. I like to work on
this in the future but due to recent events in my life I have to abandon
such research :-(
