Good questions:
1) Do you have concurrent writes to the same file from different nodes?
  1a) No
2) How many nodes do you have?
  2a) 3 to start, probably won't go beyond 12

I appreciate alternative ideas to NFS.  NFS could possibly introduce
performance issues (comments here appreciated).  The majority of the
system is write.  I would say 80%.
