To me, the cleanest way to enable dynamic selection of the driver is to select the driver through add'l HTTP headers. For example, by sending X-Deltacloud-Driver: ec2 X-Deltacloud-Endpoint: https://eu-west-1.ec2.amazonaws.com/Sounds good, but shouldn't there be some sort of auth mechanism to "verify" that an authorized entity set those headers?
If we suspect the source of the headers, we should suspect any data in the request. If an entity can munge headers, it can munge anything else in the request - the requests currently have no signing mechanism. If this type of security is a concern, the deltacloud server should be accessed via https. The client is based on RestClient, so should support https out of the box if deltacloud is running with a valid certificate. If using a self signed certificate, the client would probably need to be modified to not validate the server cert, or given the CA for the server cert so it can validate.
