So, there are possible security issues.
I can't see a security issue. User may do a "chmod oug+rwx filename" today, giving everybody else full access to their file(s). The ability to give the same free access to only a subset of everybody don't seem dangerous to me.

ls is fixable. Possibly by extending "ls -l" to show acl's or at least indicate in some way that acl's are present. The latter may be preferable to avoid script incompatibilities, sonething like this: Arw-r--r-- 1 helge helge 140 Feb 9 1999 .bash_profile The 'A' indicates that acl(s) are present, the user may then use something like "ls --acl" and get the full acl information.
