This is nice but it only tackles the easy part of multi-environment WP configurations. If you build a site and launch it live and then get a change request from the client, you either have to do a content freeze on the live site and work on dev->staging and deploy to Live post QA OR you have to tackle the challenge of merging your new dev work into the live DB. That is the REAL issue we need a solution for in the world of WP development. RAMP is the only solution that I've found which comes close.
