At the present state of the Otemba project, there is only one proxy implemented to communicate with the Amazon SimpleDB™ cloud. So, the future implies much more extensions to manage connections to other cloud providers. Otemba does not attempt to force cloud providers to follow a specific authentication protocol, as this is unrealistic. On the contrary, it attempts to standardize the pieces that do not depend on the cloud provider, which means that connecting to a new cloud requires minimal work.
