Honestly, this looks a little bit like CouchDB + x to me
Because it is great to have the data in your database, but how do you or better an editor change it (I think hackers don't like editing content all day long and editors don't like to enter content in something like phpmyadmin).
Futon/phpmyadmin are great for entering or checking data as a developer or system administrator, but I think they are too complicated and technical for the average non-techie to manage content. That's why I built my solution.
Or can you configure Futon to have a really simple interface and also force it to only allow entry for specific keys in a document?
