With fog-external, you can use arbitrary Ruby objects as backend for Fog::Storage. This can mean a custom-written local-storage backend, or, without any more configuration, a BERT-RPC (or any other RPC implementation) remote call.

gem install fog-external

require 'fog/external/storage'

storage = Fog::Storage.new({
  :provider   => 'External',
  :delegate   => BERTRPC::Service.new('localhost', 9999).call.fog
})

You can then use storage just like any other Fog::Storage object, see the Fog docs for what's possible.. The API is compatible to the one of Fog::Local.

The delegate must respond to a number of backend methods. The delegate in the above-example uses BERT-RPC to call a server on localhost:9999, using the fog module name. See examples/example.rb for a complete example including a Ernie-powered BERT-RPC backend.
