Something like this has worked for me:
/usr -maproot=root -network AAAA:BBBB:CCCC:DDDD:EEEE:: -mask ::0

One thing I have run into was that an install of a kernel over NFS using
IPv6 can stall the mount.  I have not had time to look into it, so I do
not know what exactly triggers it (number of bytes or files?).  It has
always been while copying a kernel module.
