The v3 patches are currently under function verification tests using 
RHCS cluser suite - so far so good 
(http://people.redhat.com/wcheng/Patches/NLM/). After documenting the 
procedure and restrictions, the formal submission (to nfs list) is 
scheduled at end of this month.
                                                                                

Not sure what to do with V4 yet .. need to chat with CITI folks first.
