I would not put that in production.  The mere fact that the entire file 
is locked during transfer to the client is a show stopper, not to 
mention that when there are write conflicts to different master RW 
servers, the files become inaccessible.

I wish them luck, but I couldn't put it in a production environment 
where users didn't have shell access.
