This is definitely better than the state we have now. I looked at the 
patch. Looks fine. If you could resend the patch with BUG-id lets take 
it in.

What would be even better is if we can enhance "gluster volume status 
clients" which prints the clients connected at the moment to also print 
the min,max op-versions so that the users can get the versions of all 
clients in one command.
