GDI server (as in X server, but with GDI)

That's relatively easy. It's simple to make a 'proxy' DLL that just forwards 
certain calls (even all of them) to another, similar DLL.
The problem is that the interface to GDI(32).DLL is 'private', in that it's not 
published. Therefore, MS can change the interface and semantics of it between 
releases and even Service Packs.

I think the only way to do what you're suggesting is to write a proxy video 
driver (which has a well defined interface and also receives most calls 
forwarded by GDI). I've looked into this and it's not easy, but is possible (I 
think).
