One day I hope for more universal cloud api's so that switching between services or distributing it (if ever needed ;)) over different cloud service providers doesn't require rewrites or extra overhead.

idea, write some Cloud Service Communicator API that connects through all other api's. Another layer to add.

Shouldn't the title be "Yahoo's cloud database"... I was almost expecting another EC2.

I was waiting for something like this forever and ever when I worked there.

This looks really cool. I really hope they expose it as an API or even better release it with a permissible license for us to deploy. We need aggressive competition against SimpleDB and the large number of key-value stores we already have.

What's up with the "value" String in this example?

"addr":{"value":"700 First Ave"}

In case you're wondering, the paper and technology that this is based on is here: http://research.yahoo.com/node/2304

A bit of vaporware here. No plan to quickly open this service.
