No, it started along the same lines as this, but would then also allow you to make changes to your schema, generate the appropriate ALTER TABLE commands, and then generate views for backward compatibility so that queries already written for the old schema will keep working. Also I just planned to do it as a desktop application since there's not really any aspect to this that benefits from being web-based.
I did some post-submission brainstorming with Paul, though, and the idea morphed into a DBMS desgined to run on S3.
