Rackspace has a storage service called Cloudfiles, see http://www.rackspacecloud.com/cloud_hosting_products/files The aim of this ticket is to add support for Cloudfiles in a similar vein as the support for S3 and Azure Blob Storage. This service does expose an API, see http://www.rackspacecloud.com/cloud_hosting_products/files/api There is a Java binding for this API (released under the MIT license) available here: http://github.com/rackspace/java-cloudfiles/tree Unfortunately the Java binding code is not using Maven. We may want to write our own api implementation rather than using these bindings directly. The API definition, as of 21/02/2010, is attached to this issue. The API looks to be exposed in a RESTful way, so that would likely be the option to work against (likely similar to how we're working against S3).
