If there's none, you of course have to create one.  As long as you
keep giving the same `va_fileid' to the same file (by remembering what
files you have seen), I guess that's ok.  But then I don't know of any
distributed filesystem that acts this way (what's `same' in the text
above?).  What filesystems are like that?

Looking at some existing file systems:

NFS             - the server returns a 32-bit file-ID
AFS/Arla        - files are identified by (cell, volume, vnode,
                  uniquifier) which is hashed down to a 32 bit fileno
Coda            - same as AFS/Arla
