Such RPCs would provide an opportunity to provide several important 
types of functionality:

   1. Auditing of file access that otherwise cannot be captured when all
      data resides in the cache manager
   2. An ability to optimize Windows file open/create operations that
      combine permission checks with simultaneous lock acquisition
   3. Delete on close functionality for temporary files
   4. Distributed named pipes

I am sure that there are other reasons that I can come up with if I 
spend more than five minutes.
