Does Light Speed support Linq to Amazon Simple DB?

I am trying to use light speed to connect to a amazon simple db. I created a model by dropping a "Domain" on the designer. I am now trying to use it like this:

            context = new LightSpeedContext<AssertionModelUnitOfWork>("Default");

            using (var uow = context.CreateUnitOfWork())

            {

                Assertion assertion = new Assertion();

                assertion.Subject = "mws:TestSubject";

                assertion.Predicate = "mws:TestPredicate";

                assertion.Object = "mws:TestObject";

                uow.Add(assertion);

                uow.SaveChanges();

            }

I added a connection string in my app.config file like this:

    <add name="Default" 

         connectionString="Access Key=my-key-here;Secret Access Key=my-other-key-here"

         providerName="Mindscape Provider for Amazon SimpleDB"/>

Question: What should the provider name be - if this is supported?

I think it's interpreting this as a SQL connection... but I don't know how to tell it to use the Amazon Simple DB.
