What are you plans for managing multiple instances of win32k.sys?

what would be the point of multiple instances of win32k.sys. I  
thought once it is loaded into memory by the kernel it isn't needed  
until reboot. That was my understanding anyway...

No plans. I just thought we missed a session.c in there;-P

About multiple win32k instances: It will only be loaded into mem once 
and mapped into each session. Each session will get a copy of win32k's 
data segment. That shouldnt require that much memory? Afaik, win32k is 
totally(?) session unaware. Session = win32k code segment mapping + 
win32k data segment copy + csrss + winlogon etc.

I found this strange stuff btw: 
http://www.ncisive.com/PDFs/GGXP%2021%20Architecture.pdf. Some 
lightweight session stuff?
