Interesting article that speculates about a potential "SQL Server Live" offering from Microsoft.

"In a session called "Accessing Data Services in the Cloud," Microsoft announced a programming model and related hosted service referred to as Project Astoria. Astoria is a set of downloadable bits built on top of a part of a Microsoft data access technology called ADO.NET that allows people to model data. It includes both a way of programming against an Internet-based relational database via APIs and, potentially more interesting, the capability to create relational databases that are hosted by Microsoft."
