I haven't used it but I did attend the talk on it at the AWS conference when it was announced.
It is not using DynamoDB under the covers. It basically uses a fork of MySQL for the front end and their own storage layer built from scratch on the backend. It does use concepts from the Dynamo white paper for redundantly storing the data to disk which removes the need for MySQL style replication. But it's not using the DynamoDB service currently offered from Amazon.
