Also reminds me of Tent [1]. Brendan Eich also mentioned something like this idea in the same post where he stepped down from being CEO of Mozilla [2]. It's good to see a lot of brains working on the concept because I think there's a huge amount of potential in putting data in the customer's warehouse. I think we can achieve a much greater level of composibility of consumer services when each doesn't have to worry about being its own data warehouse.
