The unix uids/gids are being used by other things. Also, some times when
moving large groups of files between servers, I find it easier to do
rsync to save all the permissions, etc. It is nice to know that for now
I can get around that, or at least it sounds that way from what you are

However, I really would love to see a S4 compatible idmap in S3 as it is
far easier to use S3 for now on the clients.
