We have tools available through the nfs4-acl-tools package (this is on CentOS 6, for example) that offer me the ability to read and set the ACLs on the volume. I figure at some level, someone must have had an API because these tools aren't specific to the underlying filesystem as this could really be offered from anything.

Well the API is propably just stuffing blobs into extended
attributes directly from userspace. That's how most of
the NFSv4 ACLs usually get done :-(.

Of course all implementations use different blobs containing
different things to do the same thing :-).
