   OK, I follow.

   The question then is how one would implement than on a server  
using a filesystem as the backing store, which is a *very* common  
case (Apache).  The information have from the filesystem doesn't seem  
to give us enough data without doing something like checksumming the  
file.  The performance implications of that solution are rather drastic.

   Absent a workable solution, we're going to be moving Apache into  
the non-compliant category if this is a MUST-level requirement.
