Hi, I don\'t think it\'s possible at all. The DistributionAlreadyExists error is returned from Amazon, not made up by s3cmd.
Why would you like to have two distributions for a single bucket? What would be the advantages against having multiple cnames for a single distro?

I think it\'s possible because I just spoke with Amazon support and they said it was. It\'s also possible to do it through the AWS Console web interface.
The reason for multiple distributions is a work-around for CF\'s slow cache refresh. Occasionally we need to push out a change and have it happen fairly quickly. To do this, we\'ll lower the DNS TTL on the CNAME, then point the CNAME at a new distribution, and voila, no stale cache (at least on the CF side). Having these distributions come from the same bucket would make things much simpler.
