Umm.. CreateFile() is a win32 API command.
It supports a "FILE_FLAG_POSIX_SEMANTICS" attribute, which claims to allow 
case sesitive files? Does that not do anything? I would have thought that 
would give case sensitive access through the win32 API if ObCaseInsensitive 
was set to 0.

I agree however, that for the most part the Win32 subsystem's API does not 
really have much support for case-sensitive access.
It would make better sense to utilize the native NT API for case sensitive
