That is a good point. I hadn't thought about it initially, but I guess 
ACLs are different to owner/group permissions. In an ACL system there is 
no such a thing as an owner. A very good point.

Except, as you just pointed out, ACLs and owner/group semantics are so 
fundamentally different that the best ls can hope to achieve is either 
not list the owner/group at all, or list them as some special value 
(e.g. "coda"). So might as well not bother.

Just out of interest - is chowning files in coda meaningful? Or does it 
just change the ls listed info and not change access rights in any way?
