Redirecting logical desktop to separate physical desktops

Hi!

Some softwares let you connect multiple physical
desktops(Keyboard/Video/Mouse) combo’s to a single machine… basically
exporting logical desktops to separate physical d/tops…

Am researching how to enable multiple interactive desktops,multiplex
the GDI calls to the respective display drivers and etc( basically how
to achieve the above said).

Any ideas/pointers would be greatly helpful.

thanks,
Elam.
