Any plans to add support for more precise ACLs?

Currently you can only make objects public or private, it would be nice if we could allow access by email.
i.e. anonymous@gmail.com -> READ
This sort of ACL is now available for [setacl] command with --acl-grant and --acl-revoke. It still has to be added to [sync]/[put] commands though.

(Now that most of the groundwork is done it would be a nice little project for someone willing to start contributing to s3cmd ;-)
