Jeremy, before adding a new ACL format...  There is an ACL formatter and
parser in libsmbclient that's been there for a long time.  It's used for
setting and retrieving ACLs on files and folders using the extended attribute
functions.  It uses a human-readable format.  You may want to see if it
already does what you're looking for.  If that functionality is needed outside
of libsmbclient, those functions can be moved to a more generic
location.
