We had issues in the past as ZFS and Windows have a different understanding
about how to sort ACLs. In combination with shared access to Excel documents
this lead to people out locking themselves. I just thought having an independent
ACL store would solve that problem for me :)

Are you using vfs_zfsacl and did you ever run into the problems I mentioned?
