I think you misunderstood Eric's comment.  He wasn't suggesting that the use of an OST pool would set the user, group, or ACL of a file created within that pool.  That would indeed be confusing to users.

Rather, Eric was suggesting that there should be a user/group/ACL permission check for the _use_ of a particular pool, so that only allowed users/groups could access the "SSD" pool, for instance.  That has been under discussion for a long time already, and is a natural extension of the base OST pool functionality.  Extending this further to allow and/or select pools based on the originating client NID or the filename also makes sense.
