Avati,
  How can this work?  If I have a tree of files (200,000 files) and I 
update this tree and maybe 30,000 files are added/changed/deleted then 
are you saying that we need to open() all 30,000 files on client0 for 
them to be replicated to the other bricks?  What about the deleted 
files?  No way to open() those.
