That's not really different to how it is implemented, now.
Actually smss is good for managing and startup of sub systems, like 
csrss.exe and csrss.exe + win32k.sys make up the GUI. Thus either write 
a win32-app or just a smsss replacing native app.

I wonder why we do not utilize a win32-app as 1st step setup?
