Yes -- but you didn't read my question. My question was about applying "Upload Rules" to a bucket. But that's okay -- thanks for your response. I'm guessing that ACLs are not a supported rule.

Yes -- but that applies to files that are already in the bucket. The "Upload Rules" features is applied to files that you upload from your local source to Amazon S3. The current behavior requires that (a) you remember to change the ACL so that files are publicly accessible, and (b) you have to manually select use the drop-down menu to apply Read permission. The "Upload Rules" is perfect, except it doesn't include the ability to apply ACLs.
