 My patch is IPv4/IPv6/DNS agnostic - it ought to work either way.  NFSv4 =
 might be a problem due to the syntax differences in /etc/exports =
 (/etc/zfs/exports).
 
 All my patch does is use ';' as a special character to allow multiple =
 values (like you want) for each export.  Each value is prefixed by the =
 mount point and written to /etc/zfs/exports.
 
 
 I'm still running it - but it's for a home file server where I want to =
 restrict "root" access from certain VPNs.  Given that all it does is =
 change the output to /etc/zfs/exports, which is handled by the regular =
 NFS export mechanism, I don't think that there should be any significant =
 difference between home and production/enterprise use - unless NFS =
 exports keel over when there's hundreds of mount points (easy to do with =
 ZFS) rather than tens.  My home set up is exporting only 25 mount =
 points.
