OK, my understanding was that euca-upload-bundle is talking directly to
an S3-like backend, so if we want to support "the EC2 way of registering
images" we need some S3-compatible server...
For serious deployments I guess we would use Swift S3 frontend. For demo
cases, do we need a simpler solution ? And if yes, which one ?
