The idea is to provide a 'local' storage driver. This will provide developers with the ability to implement storage features with libcloud such that it can be deployed on a cloud platform or over local file-systems (for eg: over a local disk or a n/w mounted storage). This will allow for hybrid deployments where the storage layer can be altered via config changes.
In addition, this also let's users play around with the library without the need to access a cloud system
A sample implementation could
- use the 'key' argument as the base file-system where the objects will be stored
- use a file-system hierarchy to represent containers and objects
